* Replace our ancient dtoa/strtod implementation with the gdtoaDavid Schultz2003-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

* Back out "drop first N values" method of removing monotonically increasedAndrey A. Chernov2003-02-171-7/+1
| | | | | | | | | | | | | | | | | | seed->first value correlation. It breaks rand_r()... Other possible methods like shuffling inside aray will breaks rand_r() too, because it assumes only one word state, i.e. nothing extra can be added after seed assignment in srand(). BTW, for old formulae seed->first value correlation is not so monotonically increased as with other Linear Congruential Generators of this type only becase arithmetic overflow happens. But overflow affects distribution and lower bits very badly, as many articles says, such type of overflow not improves PRNG. So, monotonically increased seed->first value correlation problem remains... Notes: svn path=/head/; revision=111026

Its BSD adaptation tries to fight it by mapping 0 to 2147483647 after calculation, but this method not works since 2147483647 seed returns to 0 again on the next interation.

* Define `Sudden_Underflow' when compiling for the AlphaRobert Drehmel2002-11-141-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | architecture, mainly to avoid getting a SIGFPE signal sent when calling strtod(3) with certain input. The SIGFPE has been sent because the code was not aware that a Gradual Underflow is handled in software via traps on the Alpha architecture, but is not implemented in our Alpha kernel layer. With `Sudden_Underflow' defined, strtod(3) should not depend on Gradual Underflow and adjust its calculations accordingly, which means that other, more subtle errors than the sending of SIGFPE could be solved by this.
