24 |
The __asin()__ function calculates the arc sine of |
| |
|
25 |
''x''; that is the value whose sine is ''x''. If |
| |
|
26 |
''x'' falls outside the range -1 to 1, __asin()__ |
| |
|
27 |
fails and ''errno'' is set. |
| |
|

|
| |
|

|
| |
|
31 |
The __asin()__ function returns the arc sine in radians |
| |
|
32 |
and the value is mathematically defined to be between -PI/2 |
| |
|
33 |
and PI/2 (inclusive). |
