floor function

Input type	Output type
float complex	int complex

This function returns the largest integer smaller than or equal to the argument for float arguments and returns the result. For complex arguments, the function is defined as follows:

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

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

Examples:

floor(3.2)       ; 3
floor(3.8)       ; 3
floor(6)         ; 6
floor(-3.2)      ; -4
floor(-3.8)      ; -4
floor((3.2, 7))  ; (3, 7)
