Fixed point math library for c
WebDec 14, 2011 · You have a 4.28 fixed point number, and you want to divide by a 4.28 number. You find the precision after division by subtracting the precision of the numerator from the denominator, so a straight divide would give 4.28 - 4.28 = 0 -- no significant bits. Obviously this won't work. 1.5 [4.28] 0x18000000 / 2.0 [4.28] 0x20000000 = 0? [0.00] … WebJul 12, 2024 · There numerous fixed-point mathematics libraries around the internet, such as fixed_point or the Compositional Numeric Library for C++. If you are looking for a reliable solution to utilize long-term, spend some time to review these libraries to identify candidates for integration.

WebDec 10, 2024 · Essentially, yes, because you can specify that your fixed point numbers are 32 or 64 bits, and they will be on all systems. Floating point numbers may be 32 or 64-bit, but the hardware may actually use 48 or 96 bits to do the calculation and convert to 32 or 64 bits at the end resulting in differences between different types of hardware.
WebSep 10, 2024 · Introduction to fixed-point math and CMSIS-DSP Unlike floating-point operations, fixed-point math numbers represent real number with less precision as they have a fixed number of bits to represent a number before and after the decimal point. WebJun 14, 2006 · Microcontrollers don’t use the floating point emulation, and PCs don’t use the math coprocessor. With some tweaking, I have used it for basic animation and audio processing. The fixed point library is very KISS. There is a class called “fixed” that essentially creates a new variable type similar to float or double.
