Class ASin
Version	1.0
Modified	08-MAR-2026 11:05:32.00
Code	rt_plc_macro_div.h

 ASin calculates the arc sine of the input.
 The input should be in the range  -1 / FactorIn to 1 / FactorIn, otherwise
 the output is undefined.
 The result is in radians between -PI / 2 * FactorVal and PI / 2 * FactorVal.

RtBody attributes pwr_sClass_ASin
