Hello,
can somebody explain why we have these defines in sys/powerpc/include/float.h ?
#define LDBL_MANT_DIG DBL_MANT_DIG #define LDBL_EPSILON DBL_EPSILON #define LDBL_DIG DBL_DIG #define LDBL_MIN_EXP DBL_MIN_EXP #define LDBL_MIN DBL_MIN #define LDBL_MIN_10_EXP DBL_MIN_10_EXP #define LDBL_MAX_EXP DBL_MAX_EXP #define LDBL_MAX DBL_MAX #define LDBL_MAX_10_EXP DBL_MAX_10_EXP
I mean, why do we use the DBL_* for the LDBL instead of defining them like this:
#define LDBL_MANT_DIG 64 #define LDBL_EPSILON 1.0842021724855044340E-19L #define LDBL_DIG 18 #define LDBL_MIN_EXP (-16381) #define LDBL_MIN 3.3621031431120935063E-4932L #define LDBL_MIN_10_EXP (-4931) #define LDBL_MAX_EXP 16384 #define LDBL_MAX 1.1897314953572317650E+4932L #define LDBL_MAX_10_EXP 4932
The float.h itself states that it is derived from: from: FreeBSD: src/sys/i386/include/float.h,v 1.8 1999/08/28 00:44:11
Having a look into src/sys/i386/include/float.h shows that the LDBL_* are defined as the above.
Are there missing issues in libc or so?
TIA, Regards, Andreas
