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.
