o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to , and provide double_t and float_t typedefs in . o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to and others (FLT_EVAL_METHOD, DECIMAL_DIG) to via . o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'.

long doubles at the moment (printf truncates them to doubles). However, long doubles to appear to work to the ranges listed in this commit on both -stable (4.5) and -current. There may be some slight rounding issues with long doubles, but that's an orthogonal issue to these constants. I've had this in my local tree for 3 months, and in my company's local tree for 15 months with no ill effects. Obtained from: NetBSD Not likely to like it: bde
