Macros for math limits.
Overview
The macro names given in the following list must use the values specified. These constant expressions are suitable for use in #if preprocessing directives.
| #define FLT_DIG | 6 |
| #define FLT_MANT_DIG | 24 |
| #define FLT_MAX_10_EXP | +38 |
| #define FLT_MAX_EXP | +128 |
| #define FLT_MIN_10_EXP | -37 |
| #define FLT_MIN_EXP | -125 |
| #define FLT_RADIX | 2 |
| #define FLT_MAX | 0x1.fffffep127f |
| #define FLT_MIN | 0x1.0p-126f |
| #define FLT_EPSILON | 0x1.0p-23f |
The macro names given in the following list (available if the double option is supported) must use the values specified. These constant expressions are suitable for use in #if preprocessing directives.
| #define DBL_DIG | 15 |
| #define DBL_MANT_DIG | 53 |
| #define DBL_MAX_10_EXP | +308 |
| #define DBL_MAX_EXP | +1024 |
| #define DBL_MIN_10_EXP | -307 |
| #define DBL_MIN_EXP | -1021 |
| #define DBL_MAX | 0x1.fffffffffffffp1023 |
| #define DBL_MIN | 0x1.0p-1022 |
| #define DBL_EPSILON | 0x1.0p-52 |
The macro names given in the following list must use the values specified. These constant expressions are suitable for use in #if preprocessing directives. An application that wants to use half and halfn types will need to include the #pragma OPENCL EXTENSION cl_khr_fp16(3clc) : enable directive.
| #define HALF_DIG | 3 |
| #define HALF_MANT_DIG | 11 |
| #define HALF_MAX_10_EXP | +4 |
| #define HALF_MAX_EXP | +16 |
| #define HALF_MIN_10_EXP | -4 |
| #define HALF_MIN_EXP | -13 |
| #define HALF_MAX | 0x1.ffcp15h |
| #define HALF_MIN | 0x1.0p-14h |
| #define HALF_EPSILON | 0x1.0p-10h |
The macro names given in the following list must use the values specified. These constant expressions are suitable for use in #if preprocessing directives.
| #define CHAR_BIT | 8 |
| #define CHAR_MAX | SCHAR_MAX |
| #define CHAR_MIN | SCHAR_MIN |
| #define INT_MAX | 2147483647 |
| #define INT_MIN | (-2147483647- 1) |
| #define LONG_MAX | 0x7fffffffffffffffL |
| #define LONG_MIN | (-0x7fffffffffffffffL- 1) |
| #define SCHAR_MAX | 127 |
| #define SCHAR_MIN | (-127 - 1) |
| #define SHRT_MAX | 32767 |
| #define SHRT_MIN | (-32767- 1) |
| #define UCHAR_MAX | 255 |
| #define USHRT_MAX | 65535 |
| #define UINT_MAX | 0xffffffff |
| #define ULONG_MAX | 0xffffffffffffffffUL |
