MINEXPONENT(3I)					       Last changed: 1-6-98

NAME
     MINEXPONENT - Returns the minimum (most negative) exponent of a real
     number in the numeric model

SYNOPSIS
     MINEXPONENT ([X=]x)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     Fortran 90

DESCRIPTION
     The MINEXPONENT intrinsic function returns the minimum (most negative)
     exponent of a real number in the numeric model representing numbers of
     the same type and kind type parameter as the argument.  The real
     number model is defined in the MODELS(3I) man page.  It accepts the
     following argument:

     x	  Must be of type real.	 It can be scalar or array valued.

     MINEXPONENT is an inquiry function.  The name of this intrinsic cannot
     be passed as an argument.

RETURN VALUES
     The result is a default integer scalar.  The result has the value e
									min
     as defined in the model, which represents numbers of the same type and
     kind type parameter as x.

EXAMPLES
     On UNICOS systems, except for CRAY T90 systems that support IEEE
     floating-point arithmetic, MINEXPONENT(X) has the value -8188 for real
     X.

     On IRIX systems, MINEXPONENT(X) has the following values:

     * -125 for real (KIND=4) X

     * -1021 for real (KIND=8) X

     * -967 for real (KIND=16) X

     On CRAY T90 systems that support IEEE floating-point arithmetic,
     MINEXPONENT(X) has the following values:

     * -125 for real (KIND=4) X

     * -1021 for real (KIND=8) X

     * -16381 for real (KIND=16) X

     On UNICOS/mk systems, MINEXPONENT(X) has the following values:

     * -125 for real (KIND=4) X

     * -1021 for real (KIND=8) X
