How do I convert between big-endian and little-endian values in C++? http://stackoverflow.com/questions/105252/how-do-i-convert-between-big-endian-and-little-endian-values-in-c unsigned values they work for signed integers as well. For floats and doubles it's more difficult as with plain integers as these.. in the host machines byte order. You can get little endian floats on big endian machines and vice versa. Other compilers have..
32-bit to 16-bit Floating Point Conversion http://stackoverflow.com/questions/1659440/32-bit-to-16-bit-floating-point-conversion bit numbers I just need to decrease the size of the 32 bit floats so they can be sent over the network.

How to parse space-separated floats in C++ quickly? http://stackoverflow.com/questions/17465061/how-to-parse-space-separated-floats-in-c-quickly to parse space separated floats in C quickly I have a file with millions of lines each line.. I have a file with millions of lines each line has 3 floats separated by spaces. It takes a lot of time to read the file.. to split it but I don't know how to convert strings to floats and I'm not quite sure it's the best way. I don't mind if the..
