💖 MACROS AND LIMITS 💖

okay bestie, welcome to the OpenCL Manual page for MACROS AND LIMITS(3clc) — yes the title is literally in all caps like that, she's dramatic, we love her 🎀

✨ NAME ✨

Macros_and_Limits — macros for math limits, and bestie, that's the whole vibe 💅

🌸 DESCRIPTION 🌸

The macro names in the list below must use the values specified. These constant expressions are suitable for use in #if preprocessing directives. no cap, the numbers are the numbers 📌

#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 in the next list — these ones are only available if the double option is supported — must use the values specified. These constant expressions are suitable for use in #if preprocessing directives. slay 🦋

#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 in the following list must use the values specified. These constant expressions are suitable for use in #if preprocessing directives. Also, heads up: an application that wants to use half and halfn types will need to include the #pragma OPENCL EXTENSION cl_khr_fp16(3clc) : enable directive. like, you literally cannot skip that step 🫶

#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 in the following list must use the values specified. These constant expressions are suitable for use in #if preprocessing directives. int energy, iconic behavior ✨

#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

⭐ NOTES ⭐

  1. OpenCL Specification page 252, section 6.12.2.1 - Floating-point macros and pragmas
fr fr, that's the whole page. every macro, every value, every directive, exactly where it belongs 🌟

and that's a wrap, bestie — this beauty is brought to you by The Khronos Group, dated 01/14/2021, and she's the MACROS AND LIMITS(3clc) page. bye ilysm, go compile something cute 💖🦋🌸
