Rostislav Vasilikhin	c6a3a18894	SoftFloat integrated (#8668 ) * everything is put into softfloat.cpp and softfloat.hpp * WIP: try to integrate softfloat into OpenCV * extra functions removed * softfloat made stateless * CV_EXPORTS added * operators fixed * exp added, log: WIP * log32 fixed * shorter names; a lot of TODOs * log64 rewritten * cbrt32 added * minors, refactoring * "inline" -> "CV_INLINE" * cast to bool warnings fixed * several warnings fixed * fixed warning about unsigned unary minus * fixed warnings on type cast * inline -> CV_INLINE * special cases processing added (NaNs, Infs, etc.) * constants for NaN and Inf added * more macros and helper functions added * added (or fixed) tests for pow32, pow64, cbrt32 * exp-like functions fixed * minor changes * fixed random number generation for tests * tests for exp32 and exp64: values are compared to SoftFloat-based naive implementation * minor warning fix * pow(f, i) 32/64: special cases handling added * unused functions removed * refactoring is in progress (not compiling) * CV_inline added * unions {uint_t, float_t} removed * tests compilation fixed * static const members -> static methods returning const * reinterpret_cast * warning fixed * const-ness fixed * all FP calculations (even compile-time) are done in SoftFloat + minor fixes * pow(f, i) removed from interface (can cause incorrect cast) to internals of pow(f, f), tests fixed * CV_INLINE -> inline * internal constants moved to .cpp file * toInt_minMag() methods merged into toInt() methods * macros moved to .cpp file * refactoring: types renamed to softfloat and softdouble; explicit constructors, etc. * toFloat(), toDouble() -> operator float(), operator double() * removed f32/f64 prefixes from functions names * toType() methods removed, round() and trunc() functions added * minor change * minors * MSVC: warnings fixed * added int cvRound(), cvFloor, cvCeil, cvTrunc, saturate_cast<T>() * typo fixed * type cast fixed	8 years ago

Adil Ibragimov	8a4a1bb018	Several type of formal refactoring: 1. someMatrix.data -> someMatrix.prt() 2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex ) 3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>() 4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions	10 years ago
Roman Donchenko	7ea1bf3cf0	Fixed several problems found by PVS-Studio. This fixes all problems from the article "Checking OpenCV with PVS-Studio" <http://www.viva64.com/en/b/0191/> that are not already fixed and are not in 3rdparty or the legacy module. The problems fixed are two instances of useless code and one instance of unspecified behavior (right-shifting a negative number).	11 years ago

Artanis	993522598b	Add implementations for Mat::zeros() and Mat::ones() In class Mat, "static MatExpr Mat::zeros(int ndims, const int* sz, int type)" and "static MatExpr Mat::ones(int ndims, const int* sz, int type)" are declared but never implemented. That means we can see their manuals from "http://docs.opencv.org/modules/core/doc/basic_structures.html" but we can't use them. Here I tried to finish their implementation. I have also changed MatOp_Initializer::assign to make it support multi-dimension Mat. Test cases are added in test_math.cpp as well.	12 years ago
