Any smart way to convert a float like this: float f = 711989.98f; into a decimal (or double) without losing precision?
I was trying to divide (float)200 / (float)500 but the result is 0.0. Why is this so and how ca开发者_如何学Gon we have 0.4 as the result? Thanks a lot.It is a very common mistake, every programmer ma
I am doing some performance critical work in C++, and we are currently using integer calculations for problems that are inherently floating point because "its faster". This causes a whole lo
HI, I am trying to use therobust predicates for computational geometry fromJonathan Richard Shewchuk.
Anyone knows where can I find the floating functions for non FPU processor (SH-3) called __mulsf3, __divsf3, 开发者_高级运维__addsf3, __subsf3, __ltsf2 and __floatsisf. I read that those functions are
I\'m using MSVC++, and I want to use the special value INFINITY in my code. What\'s the byte patt开发者_JS百科ern or constant to use in MSVC++ for infinity?
In my app, i\'ve created the TList type list where i store the pointers to 1 string and 2 float(real) values for every 3 items.
What determines the default setting of the x87 FPU control word -- specifically, the precision control field? Does the compiler set it based on the target processor? Is there a compiler option to chan
I am coding up an implementation of Interpolation Search in C. The question is actually rather simple, I need to use the floating operations to do linear interpolation to find the correct index which
It\'s 开发者_高级运维123.98699999999999 ! Why is that?See Why can\'t decimal numbers be represented exactly in binaryThe Python FAQ and tutorial address this issue pretty well, I think.More generally
