All these functions will manipulate character strings to fit your needs. Functions can use into conditional node and populate variable node and keep the result in a variable.

There are 3 groups of functions :

1. Character String Functions
2. Mathematics functions
3. Others functions

• $tctosec : This is the only mathematics function which must be encapsulated with quotes(“01:21:12:05”)
• Functions that accept numbers do not need to be encapsulated with quotes.
• All functions can be nested (functions within functions).

  Usage description : $function(input-1 = "string", input-2 = integer[, optional input-3 = "string"/integer])

• $round : Round number to nearest decimal.If number of output decimals is omitted then the function will return an integer.
• $roundd : Round number down to nearest integer.
• $roundu : Round number up to nearest integer.

Usages:
$round(number to round = number/%f_variable%[, number of output decimals = integer/%i_variable%])
$roundd(number to round = number/%f_variable%)
$roundu(number to round = number/%f_variable%)

• $inttotc : Converts an integer to a TC time code.
• $tctosec : Converts a TC time code to seconds.

Usages:
$inttotc(input integer = integer/%variable%, frames per second, float = float/%i_variable%)
$tctosec(input time code, string = “string/%variable%”, frames per second, float = float/%i_variable%)

• $abs : Returns the absolute value of a number.
• $log : Returns the natural logarithm of a number.
• $random : Returns a random integer number between two integers.

Usages:
$abs(input number= number/%variable%)
$log(input number= number/%variable%)
$random(input integer = integer/%variable%, input integer = integer/%variable%)
