Parameters

fValue
Value to get the arc sine of.

Description

Arc sine is the inverse of the sin() function. Thus, given an fValue that is some ratio of the opposite side to the hypotenuse of a right triangle, asin() returns the appropriate angle (in degrees) of that triangle. asin() returns a value from -90 to 90 or returns zero if fValue is greater than 1 or fValue less than -1.
