Functions in Expressions

View the list of available functions in POSTFEKO.

Table 1. Mathematical functions supported in expressions.
sin cos tan cot	Trigonometric functions (arguments expected in radians).
arcsin arccos arctan arccot	Trigonometric inverse functions (results in radians).
atan2	`atan2(y,x)` yields arctan(y/x) in the range - $π$ ... $π$ .
sinh cosh tanh	Hyperbolic functions
fmod	`fmod(a,b)` returns the remainder of the division `a`/`b`.
deg	Converts radians to degrees.
rad	Converts degrees to radians.
log	Logarithm to base 10
ln	Natural logarithm
exp	Exponential function
sqrt	Square root
abs	Absolute value
step	`step(x)` is 1 when x>0; otherwise it is 0.
ceil	Rounded upwards
floor	Rounded downwards
min max	`min(a,b)` gives the minimum of the two arguments. `max(a,b)` gives the maximum of the two arguments.
