Transform  Numbers
Transforms which appear in the template list when a numeric field of
type float32, float64,
int8, int16,
int32, int64, uint8, uint16,
uint32, or uint6,
has been picked in the Transform
pane. Operations typically allow choice of numeric type
for the Result destination. For operations on numeric vectors,
that is, ordered sets of numbers, see the Transform  Numeric Vectors
topic.

Arithmetic 
Basic arithmetic
operations, automatically providing choice of a second parameter,
specified in the Value
box and typically allowing a field, a specific value, or an expression,
for operations that use an additional parameter. Save
the result into the specified Result destination using the specified
numeric type.
 absolute value (abs)
 Compute
the absolute value of the source field number. Absolute
value leaves positive numbers unchanged and converts negative
numbers into their positive equivalents.
 add (+)  Add the
Value to the source field number.
 cube  Compute
the cube of the source field number.
 cube root (cbrt)
 Compute the cube root of the source field number.
 divide (/)  Divide
the source field number by the Value.
 divide integral (div)
 Divide the source field number by the Value and discard
any fractional part.
 divide remainder (mod)
 A classic modulo operation (the remainder
(of a congruence) function): Divide the source field
number by the Value and retain only the fractional part as
a nonfractional whole number.
 error (erf)  Compute the error
function (also
called erf(z) ) of the source field number.
 error complement (erfc)
 Compute the complementary
error function (also
called erfc(z) ) of the source field number.
 exponent (exp)
 The exponential
function:
Compute e to the power of the source field number.
For
anything but relatively small numbers in the source field
such exponentiation results in numbers larger than can be
represented in most types and thus returns a NULL.
 exponent binary (exp2)
 Also known as the power of 2: Compute 2
to the power of the source field number. If the source field has values 1, 2, 3,... the result of a binary exponentiation will be 2, 4, 8,.... For anything but relatively
small numbers in the source field such exponentiation results
in numbers larger than can be represented in most types and
thus returns a NULL.
 exponent decimal (exp10)
 Also known as the power of 10: Compute 10
to the power of the source field number. If the source field has values 1, 2, 3,... the result of a decimal exponentiation will be 10, 100, 1000,.... For anything but relatively
small numbers in the source field such exponentiation results
in numbers larger than can be represented in most types and
thus returns a NULL.
 gamma (tgamma)
 Compute
the gamma
function of the
source field number.
 gamma logarithm (lgamma)
 Compute
the natural
logarithm of the gamma
function of the
source field number.
 logarithm (log)
 Compute the base
e logarithm (also
called the natural
logarithm)
of the source field number.
 logarithm binary (log2)
 Compute the base
2 logarithm (also
called the binary
logarithm)
of the source field number.
 logarithm decimal (log10)
 Compute the base
10 logarithm (also
called the common
logarithm)
of the source field number.
 multiply (*) 
Multiply the source field number by the Value number.
 power (pow)  Compute the source field to the power of the
specified Value. A power of 1 is the source field number unchanged, a power of 2 is the source field number squared, and a power of 3 is the source field number cubed.
 reciprocal  One
divided by the source field number. The reciprocal is also the source field number
to the power of 1,
another way of saying the same thing. The reciprocal of zero
is undefined, and thus returns a NULL.
 sign (sign)  Report
if the source field number is positive (return 1)
or negative (return
1). The sign of zero is 0.
 sign invert  Multiply
the source field number by 1,
thus inverting the sign of the number.
 square  Compute
the square of the source field number (the number multiplied
by itself).
 square root (sqrt)
 Compute the square root of the source field number.
 subtract () 
Subtract the Value from the source field number.
 subtract from ()
 Subtract the source field number from the Value.

Bit Logic 
Perform a bitwise
logical operation on the source field, using the specified field,
value, or expression for and, or, and xor
operations, and save the result into the specified Result
destination using the specified numeric type.
 and  Bitwise logical
AND operation between the source field and the second specified
field, value or expression result.
 not  Bitwise logical
inversion changing bits from 1 to 0 and from 0 to 1.
 or  Bitwise logical
OR operation between the source field and the second specified
field, value or expression result.
 xor  Bitwise logical
XOR operation between the source field and the second specified
field, value or expression result.

Copy 
Copy into the specified
numeric Result destination the values in the source field, using
the specified numeric type. 
Expression 
Save the numeric
result of the given expression
into the specified numeric Result destination, creating new fields using
the specified numeric type. 
Hyperbolic 
Basic hyperbolic
trigonometric operations, allowing choice of radial unit from
Arc Minute, Arc
Second, Degree
or Radian. Save
the result into the specified Result destination using the specified
numeric type.
 hyperbolic arc cosine
(acosh)  Compute the hyperbolic
arc cosine of the source field number.
 hyperbolic arc sine (asinh)
 Compute the hyperbolic arc sine of the
source field number.
 hyperbolic arc tangent
(atanh)  Compute the hyperbolic
arc tangent of the source field number.
 hyperbolic cosine (cosh)
 Compute the hyperbolic cosine of the
source field number.
 hyperbolic sine (sinh)
 Compute the hyperbolic sine of the source
field number.
 hyperbolic tangent (tanh)
 Compute the hyperbolic tangent of the
source field number.

Limit 
Limit values within a numeric field:

Round 
Rounding operations.
Save the result into the specified Result destination
using the specified numeric type. The Round
to box allows choosing the decimal position for rounding,
for example, rounding to decimal fractions like 0.001
or rounding to whole decimal positions like 10000.
 down (floor) 
Round down to the next lowest Round to position value. 400.7 would round
down to 400.
400.7
would round down to 401
(which is a smaller amount, and thus "down," from
400).
 to nearest (round)
 Round up or down to the nearest Round to position value.
When rounding to 1,
a value of 400.5
or greater fraction will get rounded up to 401
while fractional parts less than .5
will get rounded down to 400.
 to zero (trunc)
 Rounding towards zero: Equivalent to rounding down for positive
numbers, and rounding up for negative numbers.
 up (ceil)  Round
up to the next highest Round to position value. 400.2
would round up to 401.
400.2
would round up to 400
(which is a large amount, and thus "up," from 400).

Special 
Bessel function
operations, with specification of Order.
Order may be taken from a field, or specified by a value or by
an expression. Save the result into the specified Result
destination using the specified numeric type.
 Bessel 1st kind (jn)
 The nth Bessel function of the first kind: Compute
the Bessel function Jn(x) for Order n using the source field number as x. Specifying 2 for Order uses a J2(x) Bessel function. Using 0 or 1 for the Order is equivalent to using J0(x) or J1(x), respectively.
 Bessel 2nd kind (yn)
 The nth Bessel function of the second kind: Compute
the Bessel
Function Yn(x) for Order n using the source field number as x. Specifying 2 for Order uses a Y2(x) Bessel function. Using 0 or 1 for the Order is equivalent to using Y0(x) or Y1(x), respectively.

Arc Minute, Arc
Second, Degree
or Radian. Save

 arc sine (asin)
 Compute the arc sine of the source field

 arc tangent (atan)
 Compute the arc tangent of the source

Compute the cosine of the source field

 sine (sin)  Compute
the

Drinks 
A guy walks into a bar and asks for 1.014 root
beers. The bartender says, “I’ll have to charge you extra, that’s
a root beer float”.
So the guy says, “In that case, better make it a double.”
Holidays 
Why do programmers confuse Halloween with Christmas? Because
OCT 31 = DEC 25.
