I\'m trying to rescale a timestamp (fractional part of seconds only) from nanoseconds (units of 10^-9 seconds) to the lower half of an NTP timestamp (units of 2^-32 seconds). Effectively this means mu
I have a 16 bit fixe开发者_如何学运维d point processor and I want to do fixed point processing with it.I\'m looking for the correct datatype to use for unsigned 16 bit ints..
I am looking for an algorithm to multiply and divide fixed point 15.16 numbers. I already have addition and subtraction. Those were easy - simple 32-bit add and subtract. With multiply and divide, I
I\'m reading some data over a socket. The integral data types are no trouble, the System.BitConverter methods are correctly handling the conversion. (So there are no Endian issues to worry about, I th
Wha开发者_如何学编程t is fastest and most easy way of making basic arithmetic operations on strings representing real numbers in PHP? I have a string representing MySQL\'s DECIMAL value on which I wan
I have a double variable in C++ and want to print it out to the screen as a fixed decimal point number.
I have a 64-bit timestamp unpacked from a file with bin开发者_开发问答ary data, where the top 32 bits are the number of seconds and the bottom 32 bits are the fraction of the second.I\'m stuck with ho
Can anyone please let me know What will be the difference between these approcahes when I convert fixed to float and float to fixed.
I\'m trying to multiply A*B in 16-bit fixed point, while keeping as much accuracy as possible. A is 16-bit in unsigned integer range, B is divided by 1000 and always between 0.001 and 9.999. It\'s bee
I am thinking recently on how floating point math works on computers and is hard for me understand all the tecnicals details behind the formulas. I would need to understand the basics of addition, sub
