**values --
machine-dependent values

## Syntax

**#include** <*values.h*>
## Description

This file contains a set of manifest constants,
conditionally defined for particular processor architectures.
The model assumed for integers is binary representation
(ones or twos complement),
where the sign is represented by the value of the high-order bit.

**BITS**(*type*)-
The number of bits in a specified
*type* (for example, **int**).

**HIBITS**-
The value of a short integer with only the high-order bit set
(in most implementations, 0x8000).

**HIBITL**-
The value of a long integer with only the high-order bit set
(in most implementations, 0x80000000).

**HIBITI**-
The value of a regular integer with only the high-order bit set
(usually the same as
**HIBITS** or **HIBITL**).

**MAXSHORT**-
The maximum value of a signed short integer
(in most implementations,
0x7FFF = 32767).

**MAXLONG**-
The maximum value of a signed long integer
(in most implementations,
0x7FFFFFFF = 2147483647).

**MAXINT**-
The maximum value of a signed regular integer
(usually the same as
**MAXSHORT** or **MAXLONG**).

**MAXFLOAT**-

**LN_MAXFLOAT**-
The maximum value of a single-precision floating-point number,
and its natural logarithm.

**MAXDOUBLE**-

**LN_MAXDOUBLE**-
The maximum value of a double-precision floating-point number,
and its natural logarithm.

**MINFLOAT**-

**LN_MINFLOAT**-
The minimum positive value of a single-precision floating-point number,
and its natural logarithm.

**MINDOUBLE**-

**LN_MINDOUBLE**-
The minimum positive value of a double-precision floating-point number,
and its natural logarithm.

**FSIGNIF**-
The number of significant bits in the mantissa of a single-precision
floating-point number.

**DSIGNIF**-
The number of significant bits in the mantissa of a double-precision
floating-point number.
