sincos took cos as sqrt(1 - sin*sin): its sign was lost and it was 0 near pi/2 (tan(pi/2) gave large, tan(-pi) the wrong sign); REAL tan and sin/cos reduced in LONGREAL with REAL pi and pi/2; REAL arcsin and arccos returned their unadjusted value after any earlier error (err stays set). in oocLowReal, scale, intpart, trunc and round treated a REAL as a 64 bit SET (RealMath.sqrt(2) was about 1E9); now with Reals.SetExpo and ENTIER. LowReal.small and LowLReal.small are the exact constants again. the math test expects the right values. |
