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

    The Sine of Angle Expressed in Degrees routine returns the sine
    of a given angle (in degrees).

    Format

      MTH$SIND  angle-in-degrees

      MTH$DSIND  angle-in-degrees

      MTH$GSIND  angle-in-degrees

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

1 - Corresponding JSB Entry Points

      MTH$SIND_R4

      MTH$DSIND_R7

      MTH$GSIND_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

    The sine of the angle. MTH$SIND returns an F-floating number.
    MTH$DSIND returns a D-floating number. MTH$GSIND returns a G-
    floating number.

3 - Argument

 angle-in-degrees

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

    Angle (in degrees). The angle-in-degrees argument is the address
    of a floating-point number that is this angle. For MTH$SIND,
    angle-in-degrees specifies an F-floating number. For MTH$DSIND,
    angle-in-degrees specifies a D-floating number. For MTH$GSIND,
    angle-in-degrees specifies a G-floating number.
