User Manual
If the value of an object of type char sign-extends when used in an expression, the value of
CHAR_MIN is the same as that of SCHAR_MIN, and the value of CHAR_MAX is the
same as that of SCHAR_MAX. If the value of an object of type char does not sign-extend
when used in an expression, the value of CHAR_MIN is 0, and the value of CHAR_MAX
is the same as that of UCHAR_MAX.
Floating Point
The < float.h > header defines macros that expand to various limits and parameters.
Macros
SHRT_MAX Maximum value for an object of type short int.
SHRT_MIN Minimum value for an object of type short int.
UCHAR_MAX Maximum value for an object of type unsigned char.
UINT_MAX Maximum value for an object of type unsigned int.
ULONG_MAX Maximum value for an object of type unsigned long int.
USHRT_MAX Maximum value for an object of type unsigned short int.
MB_LEN_MAX Maximum number of bytes in a multibyte character.
DBL_DIG Number of decimal digits of precision.
DBL_MANT_DIG Number of base-FLT_RADIX digits in the floating-point mantissa.
DBL_MAX Maximum represented floating-point numbers.
DBL_MAX_EXP Maximum integer such that FLT_RADIX raised to that power
approximates a floating-point number in the range of represented
numbers.
DBL_MAX_10_EXP Maximum integer such that 10 raised to that power approximates a
floating-point number in the range of represented value
((int)log10(DBL_MAX), and so on).
DBL_MIN Minimum represented positive floating-point numbers.
DBL_MIN_EXP Minimum negative integer such that FLT_RADIX raised to that
power approximates a positive floating-point number in the range of
represented numbers.
DBL_MIN_10_EXP Minimum negative integer such that 10 raised to that power
approximates a positive floating-point number in the range of repre-
sented values ((int)log10(DBL_MIN), and so on).
FLT_DIG Number of decimal digits of precision.
FLT_MANT_DIG Number of base-FLT_RADIX digits in the floating-point mantissa.
FLT_MAX Maximum represented floating-point numbers.
