TINY - Returns the smallest positive value for a real argument
TINY ([X=]x)
UNICOS, UNICOS/mk, and IRIX systems
Fortran 90
The TINY intrinsic function returns the smallest positive number in
the real number model that represents number of the same type and kind
type parameter as the argument. For more information on the real
number model, see the MODELS(3I) man page. It accepts the following
argument:
x Must be of type real. It may be scalar or array valued.
TINY is an inquiry function. The name of this intrinsic cannot be
passed as an argument.
The result is a scalar with the same type and kind type parameter as
x. The result has the value
e sub min-1
b , where b and e
min
(represented as "e sub min" in the previous equation) are as defined
in the real number model, which represents numbers of the same type
and kind type parameter as x.
On UNICOS systems, TINY(X) has a value that approximates
-8188
2 for real X.
On CRAY T90 systems that support IEEE arithmetic, TINY(X) has values
that approximate the following:
-125
* 2 for real (KIND=4) X
-1021
* 2 for real (KIND=8) X
-16381
* 2 for real (KIND=16) X
On UNICOS/mk systems, TINY(X) has values that approximate the
following:
-125
* 2 for real (KIND=4) X
-1021
* 2 for real (KIND=8) X
On IRIX systems, TINY(X) has values that approximate the following:
-125
* 2 for real (KIND=4) X
-1021
* 2 for real (KIND=8) X
-967
* 2 for real (KIND=16) X
