### NAME[Toc][Back]

```     - return scalar values related to parameters of an	associated model
```

### SYNOPSIS[Toc][Back]

```     digits (x)
epsilon (x)
huge (x)
maxexponent (x)
minexponent (x)
precision (x)
range (x)
tiny (x)
```

### DESCRIPTION[Toc][Back]

```     These Fortran 90 inquiry functions	return scalar values that describe
parameters	of a model which represents numbers of the type	and type
parameters	of argument x; the value of the	argument need not be defined,
if	a pointer it may be disassociated, if an array it need not be
allocated.	It must	be of integer or real type.

The digits	function returns an integer with the number of significant
digits in the model for x.

The epsilon function returns the difference between 1 and the next
nearest representable number amongst real types of	the same type and kind
as	x.

The huge function returns the largest number that can be represented in
the same type and kind as x.  The tiny function is	similar, but
represents	the smallest number instead of the largest.

The maxexponent function returns the largest exponent for real numbers of
the the same type and kind	as x.  The result is an	integer. The
minexponent function is similiar, but returns the smallest	exponent for
real numbers of the the same type and kind	as x.

The precision function returns an integer with the	decimal	precision for
real numbers of the same type and kind as x.

The radix function	returns	an integer with	the base of integer or real
numbers of	the same type and kind as x.

The range function	returns	an integer with	the decimal exponent range for
integer or	real numbers of	the same type and kind as x.
