sqrt function
| Input type | Output type |
| float complex | float complex |
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.
