Assume this much: I\'m using a 16.16 fixed point system. System is 32 bit. CPU has no floating point processor.
I would have assumed that GL_FIXED was faster, but the iPhone docs actually say to use GL_FLOAT because GL_FIXED has to be converted to GL_FLOAT. Is it the same on Android? I suppose it varies by phon
I have a formula which calculate position for Y, here it is: double y = ...; double minX = ..; double scaleY = ..;
I have an application which is using 24 bit fixed point calculation.I am porting it to a hardware which does support floating point, so for speed optimization I need to convert all fixed point based c
Is converting Fixed Pt. (fixed n bit for fraction) to IEEE double safe ? ie: does IEEE double format can represent all numbers a fixed point can represent ?
I am writing a class for handling decimal numbers, e.g. \"123.456\". I want one function for extracting the digits before the decimal point (123), and one function to extract the digits after the deci
Most people seem to want to go the other way. I\'m wondering if there is a fast way to convert fixed point to floating poin开发者_运维技巧t, ideally using SSE2. Either straight C or C++ or even asm wo
Does anyone know a (preferably fast) way to calculate the sine of an angle in 4.12 fixed point? (where the result is either 32768ths of a c开发者_JAVA技巧ircle or degrees)
