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

    The Natural Logarithm (H-Floating Value) routine returns the
    natural (base e) logarithm of the input argument as an H-floating
    value.

    Format

      MTH$HLOG  h-natlog ,floating-point-input-value

1 - Corresponding JSB Entry Point

      MTH$HLOG_R8

2 - Returns

    None.

3 - Arguments

 h-natlog

    OpenVMS usage:floating_point
    type:         H_floating
    access:       write only
    mechanism:    by reference

    Natural logarithm of floating-point-input-value. The h-natlog
    argument is the address of an H-floating number that is this
    natural logarithm. MTH$HLOG writes the address of this natural
    logarithm into h-natlog.

 floating-point-input-value

    OpenVMS usage:floating_point
    type:         H_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$HLOG, floating-point-input-value specifies an H-floating
    number.
