NAME

values - machine-dependent values

SYNOPSIS

#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 (one's or two's complement), where the sign is represented by the value of the high-order bit.

BITS(type) The number of bits in a specified type (e.g., int).

HIBITS The value of a short integer with only the high-order bit set.

HIBITL The value of a long integer with only the high-order bit set.

HIBITI The value of a regular integer with only the high-order bit set.

MAXSHORT The maximum value of a signed short integer.

MAXLONG The maximum value of a signed long integer.

MAXINT The maximum value of a signed regular integer.

MAXFLOAT, LN_MAXFLOAT

              The  maximum  value  of   a   single-precision
              floating-point  number,  and its natural loga-
              rithm.

MAXDOUBLE, LN_MAXDOUBLE

              The  maximum  value  of   a   double-precision
              floating-point  number,  and its natural loga-
              rithm.

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.
