For clarity, if I’m using a language that implements IEE 754 floats and I declare: float f0 = 0.f; float f1 = 1.f; …and then print them back out,...
The float data type is a single-precision 32-bit IEEE 754 floating point and the double data type is a double-precision 64-bit IEEE 754 floating point. What does it mean?...
What is the biggest “no-floating” integer that can be stored in an IEEE 754 double type without losing precision ? 8 Answers 8
It is well-known that NaNs propagate in arithmetic, but I couldn’t find any demonstrations, so I wrote a small test: #include <limits> #include <cstdio> int main(int argc, char* argv)...
Why do comparisons of NaN values behave differently from all other values? That is, all comparisons with the operators ==, <=, >=, <, > where one or both values...
I’ve read about the difference between double precision and single precision. However, in most cases, float and double seem to be interchangeable, i.e. using one or the other does...
