For the ==, <, >, <=, and >= operators, if any of the operands is not a number (Double.NaN or Single.NaN), the result of operation is false.That means that the NaN value is neither greater than, less than, nor equal to any other double (or float) value, including NaN.For more information and examples, see the Double.NaN or Single.NaN … WebMar 30, 2024 · Takeaways. When comparing floating-point values, remember: FLT_EPSILON … isn’t float epsilon, except in the ranges [-2, -1] and [1, 2]. The distance between adjacent values depends on the values in question.

The two numbers ‘a’ and ‘b’ are equal ( as (0.3 * 3) + 0.1 = 1 ) but the program results in an incorrect output. Let’s take a closer look at the numbers in the next snippet. drugs with estrogen and progesterone Thanks for your answers, they helped me a lot. I've read these materials: first and second. The answer is to use my own function for relative comparison: bool areEqualRel (float a, float b, float epsilon) { return (fabs (a - b) <= epsilon * std::max (fabs (a), fabs (b))); } This is the most suitable solution for my needs.
