NAME

       flmin, flmax, ffrac, dflmin, dflmax, dffrac, inmax - return extreme values

SYNOPSIS

       function flmin()

       function flmax()

       function ffrac()

       double precision function dflmin()

       double precision function dflmax()

       double precision function dffrac()

       function inmax()

DESCRIPTION

       Functions  flmin  and flmax return the minimum and maximum positive floating point values respectively.	Functions dflmin and dflmax return
       the minimum and maximum positive double precision floating point values.  Function inmax returns the maximum positive integer value.

       The functions ffrac and dffrac return the fractional accuracy of single and double precision floating point numbers respectively.  This	is
       the difference between 1.0 and the smallest real number greater than 1.0.

       These functions can be used by programs that must scale algorithms to the numerical range of the processor.

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 (for example, 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 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.
