ASIN(expression)

ASIN

Returns inverse sine.

expression

A numeric constant, variable, or expression for the value of the sine.

The ASIN procedure returns the inverse sine. The inverse of a sine is the angle that produces the sine. The return value is the angle in radians. p is a constant which represents the ratio of the circumference and radius of a circle. There are 2p radians (or 360 degrees) in a circle.

Return Data Type:

REAL

Example:

PI        EQUATE(3.1415926535898)     !The value of PI

Rad2Deg   EQUATE(57.295779513082)     !Number of degrees in a radian

Deg2Rad   EQUATE(0.0174532925199)     !Number of radians in a degree

CODE
