MINEXPONENT(3I) Last changed: 1-6-98
MINEXPONENT - Returns the minimum (most negative) exponent of a real
number in the numeric model
MINEXPONENT ([X=]x)
UNICOS, UNICOS/mk, and IRIX systems
Fortran 90
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.
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.
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
