You can tell Direct3D not to mess with the FPU precision by passing the D3DCREATE_FPU_PRESERVE flag to CreateDevice.. to mess with the FPU precision by passing the D3DCREATE_FPU_PRESERVE flag to CreateDevice .

Floating point vs integer calculations on modern hardware http://stackoverflow.com/questions/2550281/floating-point-vs-integer-calculations-on-modern-hardware old instructions actually used the same registers as the FPU does making it impossible to use both the FPU and MMX at the..
How do I use try…catch to catch floating point errors? http://stackoverflow.com/questions/2769814/how-do-i-use-try-catch-to-catch-floating-point-errors a different beast altogether. The exceptions a standard FPU is required to support are all defined in IEEE 754. These happen.. of two things happens 1 The exception is ignored and the FPU sets a flag indicating an error occurred in its status register.. status register s . 2 The exception isn't ignored by the FPU so instead an interrupt gets generated and whatever interrupt..
Is using double faster than float? http://stackoverflow.com/questions/3426165/is-using-double-faster-than-float but most of them at CPU level specifically within the FPU are such that the answer to your question are double operations..
C++ : Catch a divide by zero error http://stackoverflow.com/questions/4747934/c-catch-a-divide-by-zero-error an exception which I understand is not a C exception but a FPU exception I'm aware that I could check for the divisor before..
Are there any web frameworks for compiled languages like C++? http://stackoverflow.com/questions/480233/are-there-any-web-frameworks-for-compiled-languages-like-c been experimenting with Python but is seems at least on FPU less ARM architecture to be as slow as PHP. Therefore we're..
How computer does floating point arithmetic? http://stackoverflow.com/questions/6033184/how-computer-does-floating-point-arithmetic bits as o . A lot has happened here at each step the FPU has taken rather heroic measures to round the result. Two extra.. beyond what will fit in the result have been kept and the FPU knows in many cases if any or at least 1 of the remaining rightmost.. so it rounds up. The intermediate rounded values allow the FPU to carry the rightmost bit all the way over to the integer part..
