1995-05-12Changed core routines to call __ieee754_sqrt() instead of sqrt(). Ijtc
reported this enhancement to fdlibm-comments, and got the following reply: Date: Thu, 11 May 1995 14:35:25 -0700 From: Kwok.Ng@Eng.Sun.COM (KC Ng) To: fdlibm-comments@sunpro.Eng.Sun.COM, jtc@cygnus.com Subject: Re: fdlibm 5.2: why do core functions use sqrt? > I noticed that core (e_*.c) fdlibm functions like __ieee754_acos() > ensure that they call sqrt() with arguments in range (x > 0), when > they could call __ieee754_sqrt() directly. > > Since sqrt() does a lot more work (verifies x is in range, etc.) is > there any reason for this? I'd think that calling __iee754_sqrt() > would be more appropriate. .... You are right. __ieee754_sqrt should be in use with e_*.c.

1994-09-22LIBM_SCCS must be defined for the RCS ID to be defined.jtc
This library will soon be used by DJGPP. And since memory is often tight on DOS machines, there is little benifit to be had from including RCS IDs.
1994-08-18Change int -> int32_t and unsigned int -> u_int32_t to improve portabiltyjtc
to machines where int != 32 bits.
1994-08-10Float versions of math functions. From Ian Taylor (ian@cygnus.com), withjtc
minor changes by me.
