I am trying to implement my own version of pow() and sqrt() function as my 开发者_如何学Ccustom library doesn\'t have pow()/sqrt() floating point support.
This question already has answers here: 开发者_如何学Go Is floating point arbitrary precision available?
Before .Net, before math coprocessors, before IEEE-574, Microsoft defined a bit pattern for floating-point numbers. Old versions of the C++ compiler happily used that definition.
Let\'s say I have these two floats: a = 50.0 b = 1048576.0 c = a/b By printing c, I get this: 4.76837158203125e-005
Im trying to change from big endian to little endian on a double. One way to go is to use double val, tmp = 5.55;
We have 2\'s complement for integers that allows us to perform operations without worrying about the sign. That is a big help at the implementation level.
I am trying to make an array of 3 floats in Actionscript 1.0, but instead of incrementing the X & Y variables by 1, it just adds 1 to the end of the previous value.This has nothing to do with Flas
I have got several 开发者_StackOverflow社区thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings,
I have a weird math 开发者_JAVA百科calculation here.I hope someone will explain. $a = 1.85/100; $b = 1.5/100;
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
