trunc function

Input type	Output type
float complex	int complex

This function rounds the argument towards zero for float arguments and returns the result. For complex arguments, the function is defined as follows:

trunc(a + bi) = trunc(a) + trunc(b) * i

If the argument is of type int, it is first converted to float by the compiler.

Examples:

trunc(3.2)       ; 3
trunc(3.8)       ; 3
trunc(6)         ; 6
trunc(-3.2)      ; -3
trunc(-3.8)      ; -3
trunc((3.2, 7))  ; (3, 7)
