 h-exp

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

    Exponential of the input value specified by floating-point-input-
    value. The h-exp argument is the address of an H-floating number
    that is this exponential. MTH$HEXP writes the address of the
    exponential into h-exp.

 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. For MTH$HEXP, floating-point-
    input-value specifies an H-floating number.
