CubeSuite+ Ver.1.00.00 CHAPTER 3 COMPILER LANGUAGE SPECIFICATIONS Name FLT_DIG Value +6 Meaning Number of digits of a decimal numberNote 1 (q) that can round a decimal number of q digits to a floating-point DBL_DIG number of p digits of the radix b and then restore the LDBL_DIG FLT_MIN_EXP decimal number of q -125 Minimum negative integer (emin) that is a normalized floating-point number when FLT_RADIX is raised to the DBL_MIN_EXP power of the value of FLT_RADIX minus 1. LDBL_MIN_EXP FLT_MIN_10_EXP -37 Minimum negative integerlog10bemin-1 that falls in the range of a normalized floating-point number when 10 is DBL_MIN_10_EXP raised to the power of its value. LDBL_MIN_10_EXP FLT_MAX_EXP +128 Maximum integer (emax) that is a finite floating-point number that can be expressed when FLT_RADIX is DBL_MAX_EXP raised to the power of its value minus 1. LDBL_MAX_EXP FLT_MAX_10_EXP +38 Maximum value of finite floating-point numbers that can be expressed DBL_MAX_10_EXP (1 - b-p) ＊ bemax LDBL_MAX_10_EXP FLT_MAX 3.40282347E + 38F Maximum value of finite floating-point numbers that can be expressed DBL_MAX (1 - b-p) ＊ bemax LDBL_MAX FLT_EPSILON 1.19209290E - 07F specified floating-point number type and the lowest DBL_EPSILON value which is greater than 1. b1 - p LDBL_EPSILON FLT_MIN DifferenceNote2 between 1.0 that can be expressed by 1.17549435E - 38F Minimum value of normalized positive floating-point number DBL_MIN bemin - 1 LDBL_MIN Notes 1. DBL_DIG and LDBL_DIG are 10 or more in the ANSI standards but are 6 in the V850 microcontrollers because both the double and long double types are 32 bits. 2. DBL_EPSILON and LDBL_EPSILON are 1E-9 or less in the ANSI standards, but 1.19209290E07F in the V850 microcontrollers. (11) Identifier An external name must consist of up to 1022 characters and must be able to be identified uniformly. Uppercase and lowercase characters are distinguished.
