The information in this article applies to:
  • Microsoft FoxPro for MS-DOS, versions 1.02, 2.0, 2.5, and 2.5a
  • Microsoft FoxPro for Windows, versions 2.5 and 2.5a

The documentation for the ASIN() function in the "Commands & Functions" manuals for versions 1.02 and 2.0 and the "Language Reference" manual for version 2.5 lists an incorrect minimum value of -1.57079 and maximum value of +1.57079.

The actual value returned at six decimal places is 1.570796. Due to rounding, the maximum value returned if five decimal places are displayed is 1.57080. The minimum value if five decimal places are displayed is -1.57080. For example: 

   SET DECIMALS TO 5
   ?ASIN(1)        && Returns  1.57080

   SET DECIMALS TO 7
   ?ASIN(1)        && Returns  1.5707963
