of argument-1. The type of this function is numeric.
General Format
Arguments
- Argument-1 must be class numeric.
- The value of argument-1 must be greater than or equal to -1 and less than or equal to +1.
Returned Values
- The returned value is the approximation of the arcsine of argument-1 and is greater
than or equal to -pi/2 and less than or equal to +pi/2.
Note: Conversion factors from radians to degrees and Gon (grad) are specified in the section Trigonometric Functions.
- Floating-point format is used for numeric non-integer results.
