asin function
| Input type | Output type |
| float complex | float complex |
This function calculates the arcsine of the argument and returns the result. If the argument is of type int, it is first converted to float by the compiler.
Examples:
asin(1) ; 1.5708 asin(1.0) ; 1.5708 asin((1, 0)) ; (1.5708, 0)
Notes
- asin(sin(x)) is equal to x if x is within the range -pi..pi.
- The argument should not be outside the range -1..1. Otherwise this function will return an invalid value. See Invalid operations.
