VMS Help RTL Routines, MTH$, MTH$xASIND  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Given the sine of an angle, the Arc Sine in Degrees routine
    returns that angle (in degrees).

    Format

      MTH$ASIND  sine

      MTH$DASIND  sine

      MTH$GASIND  sine

      Each of the above formats accepts one of the floating-point
      types as input.

1 - Corresponding JSB Entry Points

      MTH$ASIND_R4

      MTH$DASIND_R7

      MTH$GASIND_R7

      Each of the above JSB entry points accepts one of the floating-
      point types as input.

2 - Returns

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating
    access:       write only
    mechanism:    by value

    Angle in degrees. MTH$ASIND returns an F-floating number.
    MTH$DASIND returns a D-floating number. MTH$GASIND returns a
    G-floating number.

3 - Argument

 sine

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating
    access:       read only
    mechanism:    by reference

    Sine of the angle whose value (in degrees) is to be returned. The
    sine argument is the address of a floating-point number that is
    this sine. The absolute value of sine must be less than or equal
    to 1. For MTH$ASIND, sine specifies an F-floating number. For
    MTH$DASIND, sine specifies a D-floating number. For MTH$GASIND,
    sine specifies a G-floating number.
