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

    The Exponential routine returns the exponential of the input
    value.

    Format

      MTH$EXP  floating-point-input-value

      MTH$DEXP  floating-point-input-value

      MTH$GEXP  floating-point-input-value

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

1 - Corresponding JSB Entry Points

      MTH$EXP_R4

      MTH$DEXP_R6

      MTH$GEXP_R6

      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 exponential of floating-point-input-value. MTH$EXP returns an
    F-floating number. MTH$DEXP returns a D-floating number. MTH$GEXP
    returns a G-floating number.

3 - Argument

 floating-point-input-value

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

    The input value. The floating-point-input-value argument is
    the address of a floating-point number. For MTH$EXP, floating-
    point-input-value specifies an F-floating number. For MTH$DEXP,
    floating-point-input-value specifies a D-floating number. For
    MTH$GEXP, floating-point-input-value specifies a G-floating
    number.
