94a045aa3d * Moved declarations of TFPURoundingMode,TFPUExceptionMask and TFPUPrecisionMode to System unit. Declarations in Math unit changed to aliases. 
* Changed type of softfloat_exception_mask and softfloat_exception_flags to TFPUExceptionMask, softfloat_rounding_mode to TFPURoundingMode.
- Cleaned out numerous conversions happening when getting/setting exception mask and rounding mode.

0255eb880e - Removed mathuh.inc files which are identical for all targets (except m68k, see below), their contents moved into math.pp.

141b2f7066 * arcsin and arccos: improve accuracy at small arguments by replacing sqr(1-x*x) with sqr((1-x)*(1+x)). 
* arcosh: likewise, error near 1.0 decreases approx. from 80*eps to 4*eps.
* artahn: improve accuracy by replacing ln(x+1) with lnxp1(x).

c7213b7ff1 - Math unit: don't raise EInvalidArgument exception in general math functions, this is Delphi-compatible. Delphi raises EInvalidArgument only in statistical/financial functions; general math functions execute code which causes EInvalidOp raised by hardware (or low-level system routines).
