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

    The Extended Multiply and Integerize routine (F-Floating-Point
    Values) allows higher-level language users to perform accurate
    range reduction of F-floating arguments.

1 - Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2 - Arguments

 floating-point-multiplier

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

    The multiplier. The floating-point-multiplier argument is the
    address of an F-floating number containing the number.

 multiplier-extension

    OpenVMS usage:byte_unsigned
    type:         byte (unsigned)
    access:       read only
    mechanism:    by reference

    The left-justified multiplier-extension bits. The multiplier-
    extension argument is the address of an unsigned byte containing
    these multiplier extension bits.

 floating-point-multiplicand

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

    The multiplicand. The floating-point-multiplicand argument is an
    F-floating number.

 integer-portion

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       write only
    mechanism:    by reference

    The integer portion of the result. The integer-portion argument
    is the address of a signed longword integer containing the
    integer portion of the result.

 fractional-portion

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

    The fractional portion of the result. The fractional-portion
    argument is the address of an F-floating number containing the
    fractional portion of the result.
