Description
The
asin function computes the principal value of
the arc sine of
x. A domain error occurs for arguments not in
the range [-1, +1].
Returns
The
asin function returns the arc sine in the
range [-pi/2, +pi/2] radians.
Implementation Notes
|
For arguments < -1.0, asin returns -pi/2 and sets
EDOM.
|
|
For arguments > +1.0, asin returns +pi/2 and sets
EDOM.
