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

    The Natural Logarithm routine returns the natural (base e)
    logarithm of the input argument.

    Format

      MTH$ALOG  floating-point-input-value

      MTH$DLOG  floating-point-input-value

      MTH$GLOG  floating-point-input-value

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

1 - Corresponding JSB Entry Points

      MTH$ALOG_R5

      MTH$DLOG_R8

      MTH$GLOG_R8

      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 natural logarithm of floating-point-input-value. MTH$ALOG
    returns an F-floating number. MTH$DLOG returns a D-floating
    number. MTH$GLOG 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 that is this value. For
    MTH$ALOG, floating-point-input-value specifies an F-floating
    number. For MTH$DLOG, floating-point-input-value specifies a
    D-floating number. For MTH$GLOG, floating-point-input-value
    specifies a G-floating number.
