ASIN real-valued function ASIN real-valued function Syntax ASIN (value) Function Return the size of the angle (in degrees) that has its trigonometric sine equal to value. Usage Considerations The value parameter must be in the range of -1.0 to +1.0. Any value outside this range will cause the error *Illegal value*. Parameter value Real-valued expression that defines the sine value to be considered. Details Returns the inverse sine (arcsine) of the argument, which is assumed to be in the range of - 1.0 to +1.0. The resulting value is always in the range of -90.0 to +90.0, inclusive. Examples ASIN(0) ;Returns 0 ASIN(-1) ;Returns -90 ASIN(0.1) ;Returns 5.73917047 ASIN(0.5) ;Returns 30 NOTE:
TYPE, PROMPT, and similar instructions output the results of the above examples as single-precision values. However, they are actually stored and manipulated as double- precision values. The LISTR monitor command will display real values to full precision. eV+Language Reference Guide, v2.x, 18319-000 Rev A Page 65
