Numeric functions

Reference documentation for Expressif functions in the numeric scope.

Name	Overview
absolute	Returns the absolute value of the argument value.
add	Returns the sum of the input value and the parameter value.
ceiling	Returns the smallest integer greater than or equal to the argument number.
clip	Returns the value of an argument number, unless it is smaller than min, in which case it returns min, or greater than max, in which case it returns max.
cube-power	Returns the the numeric argument value raised to the cube power.
cube-root	Returns cube root of the numeric argument value.
decrement	Returns the argument number decremented of one unit.
divide	Returns the argument number divided by the parameter value. If the parameter value is 0, it returns null.
floor	Returns the largest integer less than or equal to the argument number.
greatest-common-divisor	Returns the greatest common divisor (GCD) of the argument integer and the parameter integer. Returns null if the argument is not an integer.
human-readable-format-binary-bytes	Formats a numeric value as binary bytes using IEC prefixes.
human-readable-format-decimal	Formats a numeric value using decimal SI prefixes.
human-readable-format-decimal-bytes	Formats a numeric value as decimal bytes using SI prefixes.
increment	Returns the argument number incremented of one unit.
integer	Returns the value of an argument number rounded to the nearest integer.
invert	Returns the reciprocal of the argument number, meaning the result of the division of 1 by the argument number. If the argument value is 0, it returns null.
lowest-common-multiple	Returns the lowest common multiple (LCM) of the argument integer and the parameter integer. Returns null if the argument is not an integer.
multiply	Returns the argument number multiplied by the parameter value.
nth-root	Returns the root specified by the parameter value of the numeric argument value.
null-to-zero	Returns the unmodified argument value except if the argument value is null, empty or whitespace then it returns 0.
oppose	Returns the integer being the additive inverse of the argument meaning that their sum is equal to zero. The opposite of 0 is 0.
percent-change	Returns the percentage change from the previous numeric value to the current input value. Returns null when the input or parameter cannot be evaluated or when the previous value is zero.
power	Returns the the numeric argument value raised to the power specified by the parameter value.
round	Returns the value of an argument number to the specified number of fractional digits.
sign	Returns an integer that indicates the sign of the argument value. It returns -1 if the value is strictly negative, 0 if the value is 0 and 1 if the value is strictly positive.
square-power	Returns the the numeric argument value raised to the square power.
square-root	Returns square root of the numeric argument value.
subtract	Returns the difference between the argument number and the parameter value.
