Function Documentation

util::make_unsigned<T>::type gismo::math::abs_diff ( T  a, T  b  )

inline

Return smallest difference between two (integer)T numbers as unsigned T especially the case abs_diff(INT32_MAX, INT32_MIN) := UINT32_MAX is correct

T gismo::math::nextafter ( T  x, T  y  )

inline

For numeric types, this function returns the next representable value after x in the direction of y
