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
represented 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.
FLT_MAX_EXP Maximum integer such that FLT_RADIX raised to that power
approximates a floating-point number in the range of represented
numbers.
FLT_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(FLT_MAX)
, and so on).
FLT_MIN Minimum represented positive floating-point numbers.
FLT_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
