Double. Returns the arcsine of n.
This statement returns .999998 (rounded to six places):
ASin(.84147)
This statement returns .520311 (rounded to six places):
ASin(LogTen (Pi (1)))
This statement returns 0:
ASin(0)
This code in the Clicked event of a button catches a runtime error that occurs when an arcsine is taken for a user-entered value—passed in a variable—that is outside of the permitted range:
Double ld_num
ld_num = Double (sle_1.text)
TRY
sle_2.text = string (asin (ld_num))
CATCH (runtimeerror er)
MessageBox("Runtime Error", er.getmessage())
END TRY
