Fixed point library

WebJan 8, 2024 · Introduction The Compositional Numeric Library (CNL) is a C++ library of fixed-precision numeric classes which enhance integers to deliver safer, simpler, cheaper arithmetic types. CNL improves on numbers the same way that the STL improves on arrays and smart pointers improve on pointers. Uses include 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.
