Include: omtrig.xin |
Return type: OMX Returns: The arc sine of the floating point value. |
define external float function
asin value float x
Use asin to calculate, in radians, the arc sine (inverse sine) of a floating point number. This trigonometric function works the same way as its equivalent in the C math library.
Out-of-range values, (|x| > 1), return "not a number" (NaN).
The following sample shows how to use asin to calculate the value of the arc sine of 0.999. The result is 1.526071239626164.
include "omtrig.xin"
process
local float x initial {0.999}
output "The arc sine of x is "
|| "d" % (asin x)
|| " %n"
; Output: "The arc sine of x is 1.526071239626164"
