c++ Programming Glossary: tolerance

http://stackoverflow.com/questions/13940316/floating-point-comparison-revisited

Therefore there should be no default value for the tolerance each user should be required to supply their own hopefully based.. Sometimes no value is appropriate In some cases the tolerance cannot be relative to the values being compared neither a mathematically.. being compared neither a mathematically exact relative tolerance nor a quantized ULP tolerance. For example nearly every output..
