  Károly Balogh 6dff85df58 math: replace trunc() with int() in some functions working with floats to avoid some unnecessary int64->double conversions, as trunc returns an integer, which then has to be converted back to float 8 years ago

  sergei 161f812113 * Explicitly typecast (-longint) to longint, otherwise it becomes an int64 on 64-bit targets, causing wrong result of sign(longint). Mantis #29649. 9 years ago
  sergei 9b84581f4c + function copysign(x,y), calculates abs(x)*sign(y), private for unit math (not in interface). 9 years ago
  sergei a4ed9f3b54 * Improved sign(x) functions to be branchless in most cases. Resolves #14206. 9 years ago
  michael 88957c62e3 * Add Ceil64 and Floor64, patch from Bart Broersma (bug ID 28370) 9 years ago

  michael bb7e0f645f * Fake some types when running under FPDOC 10 years ago
  marco 3a7cde492e * finance functions by wp, mantis #26459 11 years ago
  sergei f767d9017c * Fixed sin(-0.0) to return -0.0 (was returning 0.0) 11 years ago
  sergei 57c762c8d2 + Inserted license header for AMath routines. 11 years ago
  sergei bd58adfcc9 + Added credits for functions reused from AMath/DAMath libraries. 11 years ago
  michael d45ced0221 * Added DegNormalize 11 years ago
  sergei 94a045aa3d * Moved declarations of TFPURoundingMode,TFPUExceptionMask and TFPUPrecisionMode to System unit. Declarations in Math unit changed to aliases. 11 years ago
  sergei 0255eb880e - Removed mathuh.inc files which are identical for all targets (except m68k, see below), their contents moved into math.pp. 11 years ago
  nickysn 19a39cde4a * 16-bit objpas.integer type fixes in Math.DivMod 11 years ago
  nickysn 4eb9043ac7 * x87 optimized version of math.log2() for i8086, i386 and x86_64 11 years ago
  nickysn 90b69184f1 * use a {$if defined()} sequence, instead of nested ifdefs for selecting the 11 years ago
  sergei 141b2f7066 * arcsin and arccos: improve accuracy at small arguments by replacing sqr(1-x*x) with sqr((1-x)*(1+x)). 11 years ago
  sergei 636736dda6 * log2() and log10(): replaced division by ln(base) with multiplication by reciprocal constant, this executes faster and somehow provides slightly better accuracy. 11 years ago
  sergei 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). 11 years ago
