Functions | |
Numbers of digits used for writing floating point numbers (a.k.a. precision). | |
These functions are provided to unify the handling of this issue throughout OpenMS. (So please don't use ad-hoc numbers ;-) ) If you want to avoid side effects you can use precisionWrapper() to write a floating point number with appropriate precision; in this case the original state of the stream is automatically restored afterwards. See precisionWrapper() for details. In practice, the number of decimal digits that the type can represent without loss of precision are 6 digits for single precision and 15 digits for double precision. We have and , so rounding will remove the remaining difference. Example: #define NUMBER 12345.67890123456789012345678901 std::cout << NUMBER << '\n'; // default precision, writes: 12345.7 double d = NUMBER; std::cout.precision(writtenDigits<double>(0.0)); // explicit template instantiation std::cout << writtenDigits<double>(0.0) << ": " << d << '\n'; // writes: 15: 12345.6789012346 float r = NUMBER; std::cout.precision(writtenDigits(r)); // type deduced from argument long double l = NUMBER; std::cout.precision(writtenDigits(1L)); // argument is not used, but L suffix indicates a long double double x = 88.99; std::cout.precision(15); std::cout << "15: " << x << '\n'; // writes: 15: 88.99 std::cout.precision(16); std::cout << "16: " << x << '\n'; // writes: 16: 88.98999999999999 | |
