Asin function

Syntax

Asin(value)

Description

Use the Asin function to calculate the arcsine of the given value, that is, the size of the angle whose sine is that value.

Parameters

Parameter	Description
value	Any real number between -1.00 and 1.00 inclusive, the range of valid sine values. If the input value is outside this range, an error message appears at runtime ("Decimal arithmetic error occurred. (2,110)"). Adjust your code to provide a valid input value.

Returns

A value in radians between -pi/2 and pi/2.

Example

The following example returns the size in radians of the angle whose sine is 0.5:

&MY_ANGLE = Asin(0.5);
