Function	Example	Description
if(a, b, c) (a is a boolean expression)	if(eq(5,5),5,0) =5	Returns b if the boolean expression is true (a=1) and c if the expression is false (a=0)
sig(n,x)	sig(4,2.1) =2.100	Returns x expressed to n significant digits
condition:	$a = rand(1, 20); $b = rand(1, 20); condition: not(eq($a, $b)); $c = 1/($a - $b);	The condition statement evaluates the right-hand side expression. If the expression evaluates to a nonzero value, subsequent statements are processed. Otherwise (if the condition fails), the randomization script is reprocessed from the top, with new randomization values.
decimal(n, x)	decimal(3,5.64) =5.640	Returns x expressed as a floating point number to n decimal places.
lsu(n,x)	lsu(3, 3.14159) = 0.01, (0.01 being a unit in the 3rd significant place)	Returns the least significant unit of x in the n'th place.
int(x)	int(8.740) =8	Returns the integer part of x

sum(var, start, stop, expr)	sum(i, 1, 10, i^2) =385 ( sum of the squares of the integers from 1 to 10).	Returns the result of summing the expression expr as the variable var runs through the values start to stop (inclusive).
fact(n)	fact(5) = 120 (5x4x3x2)	Computes n-factorial.
strcat(a,b,c,...)	strcat("cats ", "and", " dogs") ="cats and dogs"	It returns a string obtained by concatenating (connecting) the arguments.
min(a,b,c...)	min(5,3,9,11,4) =3	Returns the minimum value in the list.
max(a,b,c...)	max(4,8,33,1,23,5) =33	Returns the maximum value in the list.
