Header compat.h should be used instead of stdlib.h, stdbool.h, stdint.h, float.h, fenv.h,

math.h. It provides workarounds if these headers are not available or not complete.

Important: It should be included before math.h, directly or indirectly, because Intel mathimf.h

WARNING: DO NOT USE THESE MACROS: MAKE_HEX_FLOAT, MAKE_HEX_DOUBLE, MAKE_HEX_LONG.
|
|
|
|
This is a typical usage of the macros:
|
|
|
|
double yhi = MAKE_HEX_DOUBLE(0x1.5555555555555p-2,0x15555555555555LL,-2);
|
|
|
|
(taken from math_brute_force/reference_math.c). There are two problems:
|
|
|
|
1. There is an error here. On Windows in will produce incorrect result
|
|
`0x1.5555555555555p+50'. To have a correct result it should be written as
|
|
`MAKE_HEX_DOUBLE(0x1.5555555555555p-2,0x15555555555555LL,-54)'. A proper value of the
|
|
third argument is not obvious -- sometimes it should be the same as exponent of the
|
|
first argument, but sometimes not.
|
|
|
|
2. Information is duplicated. It is easy to make a mistake.
|
|
|
|
Use HEX_FLT, HEX_DBL, HEX_LDBL macros instead (see them in the bottom of the file).
|
|

HEX_FLT, HEXT_DBL, HEX_LDBL -- Create hex floating point literal of type float, double, long
|
|
double respectively. Arguments:
|
|
|
|
sm -- sign of number,
|
|
int -- integer part of mantissa (without `0x' prefix),
|
|
fract -- fractional part of mantissa (without decimal point and `L' or `LL' suffixes),
|
|
se -- sign of exponent,
|
|
exp -- absolute value of (binary) exponent.
|
|
|
|
Example:
|
|
|
|
double yhi = HEX_DBL( +, 1, 5555555555555, -, 2 ); // == 0x1.5555555555555p-2
|
|
|
|
Note:
|
|
|
|
We have to pass signs as separate arguments because gcc pass negative integer values
|
|
(e. g. `-2') into a macro as two separate tokens, so `HEX_FLT( 1, 0, -2 )' produces result
|
|
`0x1.0p- 2' (note a space between minus and two) which is not a correct floating point
|
|
literal.
