For numbers larger than 2.0 the gap between floats grows larger and if you compare floats using FLT_EPSILON then you are just doing a more-expensive and less-obvious equality check. For numbers above 16777216 the appropriate epsilon to use for floats is actually greater than one, and a compar...
cfloatcompare 25th Jan 2020, 7:29 PM Paolo De Nictolis + 6 It's because y is a float and a usual floating point number is stored as double. If you'd use double y instead you won't notice the issue. You could also write y == 0.1f to explicitly declare 0.1 to be a float. ...
How do I write floating point types in a binary file how do you check which compiler you are using in c++ How do you compare two file paths? How do you convert an std::wstring into a LPCWSTR? How do you debug a function in a dynamically loaded dll with VS 2005? How do you run ...
