Calculates the arc sine of a floating-point number.

[Format]

#include <mathf.h>

float asinf (float f);

[Parameters]

f Floating-point number for which arc sine is to be computed

[Return values]

Normal: Arc sine of f

Abnormal: Domain error: Returns not-a-number.

[Remarks]

A domain error occurs for a value of f not in the range [–1.0, +1.0].

The asinf function returns the arc sine in the range [–π/2, +π/2] by the radian.
