SYNOPSIS
#include
DESCRIPTION
This header file contains a set of manifest constants that are conditionally
defined for particular processor architectures. The model for integers is
assumed to be a ones- or twos-complement binary representation, in which the
sign is represented by the value of the high-order bit.
BITS(type) The number of bits in the specified data type
HIBITS A short integer with only the high-order bit set (0x8000)
HIBITL A long integer with only the high-order bit set (0x80000000)
HIBITI A regular integer with only the high-order bit set (the same as
HIBITL)
MAXSHORT The maximum value of a signed short integer (0x7FFF == 32767)
MAXLONG The maximum value of a signed long integer (0x7FFFFFFF ==
2147483647)
MAXINT The maximum value of a signed regular integer (the same as
MAXLONG)
MAXFLOAT The maximum value of a single-precision floating-point number
MAXDOUBLE The maximum value of a double-precision floating-point number
LN_MAXDOUBLE The natural logarithm of MAXDOUBLE
MINFLOAT The minimum positive value of a single-precision floating-point
number
MINDOUBLE The minimum positive value of a double-precision floating-point
number
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
FMAXEXP The maximum exponent of a single-precision floating-point number
DMAXEXP The maximum exponent of a double-precision floating-point number
FMINEXP The minimum exponent of a single-precision floating-point number
DMINEXP The minimum exponent of a double-precision floating-point number
FMAXPOWTWO The largest power of two that can be exactly represented as a
single-precision floating-point number
DMAXPOWTWO The largest power of two that can be exactly represented as a
double-precision floating-point number.
