1) I can find no reference to log1p in <math.h> on BSD4.2, SysV2.0, SysV3.1, nor Ultrix4.2. Is it magic? 2) What is int i; i *= 0.5; supposed to do? My cc gets it wrong (I guess) (but at least warns me). Gcc gets it right (?). (From looking at .s files). -- jim nelson nelson@ecsvax.uncecs.edu nelson@ecsvax.bitnet
