ASIN()
 To return the ARCSINE in degrees of a sine value.
------------------------------------------------------------------------------

 Syntax

      ASIN( <nSin> ) -> nDegree

 Arguments

      <nSin> is a numeric value representing a sine value.

      NOTE: Since a parameter of greater than 1 result in a math overflow,
            this function returns 0 as a result instead of a math overflow.

 Returns

      ASIN() returns the arcsine value (reverse sine) in degrees of <nSin>.

 Description

      ASIN() is a trigonometrical function that returns the arcsine value
      in degrees of a sine value.

      For radians, see ASINR().

      Accuracy is to the twelfth decimal (i.e. .00000000001)

 Examples

      ? Str( ASIN(.707106781), 5,  2)  // returns 45.00
      ? Str( ASIN(.866025403), 5,  2)  // returns 60.00
