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 inte‐
ger.
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-pre‐
cision floating-point number, and its natu‐
ral logarithm.
MINDOUBLE, LN_MINDOUBLE The minimum positive value of a double-pre‐
cision floating-point number, and its natu‐
ral logarithm.
FSIGNIF The number of significant bits in the man‐
tissa of a single-precision floating-point
number.
DSIGNIF The number of significant bits in the man‐
tissa of a double-precision floating-point
number.
