modification history
|
||||
--------------------
|
||||
01q,09nov17,lau added prototype for ldexpf (VXW6-86052)
|
||||
01p,29apr10,pad Moved extern C statement after include statements.
|
||||
01o,08jul96,ms fixed prototype for fmodf (SPR 6856)
|
||||
01n,29mar95,kdl added prototype for __fixunssfsi() (gcc callout routine).
|
||||
01m,15oct92,rrr silenced warnings
|
||||
01l,22sep92,rrr added support for c++
|
||||
01k,19sep92,kdl added prototypes for gccMathInit, gccUssInit, gccUss040Init.
|
||||
01j,30jul92,kdl changed to ANSI single precision names (e.g. fsin -> sinf);
|
||||
merged various architectures; fixed 01i mod history.
|
||||
01i,08jul92,smb merged with ANSI math.h
|
||||
01h,04jul92,jcf cleaned up.
|
||||
01g,26may92,rrr the tree shuffle
|
||||
01f,04oct91,rrr passed through the ansification filter
|
||||
-fixed #else and #endif
|
||||
-changed copyright notice
|
||||
01e,16jul91,ajm added MIPS specific externs, and made MIPS unsupported
|
||||
functions 68k dependent
|
||||
01d,28jan91,kdl added single-precision, cbrt(), hypot(); changed def's of
|
||||
irint() and iround() to int; changed def of sincos() to void.
|
||||
01c,19oct90,elr ANSI cleaned up
|
||||
01b,05oct90,dnw deleted private routines.
|
||||
01a,23aug90,elr written.
