sqrt function

This function calculates the square root of the argument and returns the result. If the argument is of type int, it is first converted to float by the compiler.

Examples:

sqrt(4)      ; 2.0
sqrt(4.0)    ; 2.0
sqrt((4,0))  ; (2,0)

Note: When using floats, the argument should not be negative. For negative float arguments, this function returns the invalid value NAN.
