Helper functions for computing floating-point differences | |
These routines are used to initialize FloatingPointDifference. They peek into some internal types from Google Test (gtest-internal.h), and duplicate some other functionality from there, but that is likely a better alternative than just copying all that code here. | |
template<typename FloatType > | |
FloatingPoint< FloatType >::Bits | floatingPointToBiasedInteger (const FloatingPoint< FloatType > &value) |
Computes biased integer representation for a floating-point value. More... | |
template<typename FloatType > | |
uint64_t | calculateUlpDifference (const FloatingPoint< FloatType > &value1, const FloatingPoint< FloatType > &value2) |
Computes the magnitude of the difference in ULPs between two numbers, treating also values of different sign. | |
template<typename FloatType > | |
void | initDifference (FloatType raw1, FloatType raw2, double *absoluteDifference, uint64_t *ulpDifference, bool *bSignDifference) |
Helper to implement the constructors for FloatingPointDifference. | |
template<typename FloatType > | |
uint64_t | relativeToleranceToUlp (FloatType tolerance) |
Converts a relative tolerance into an ULP difference. | |
Variables | |
bool | g_showExpectedExceptions = false |
Whether to print the message from expected exceptions. | |
