WebJan 4, 2024 · Some values cannot be exactly represented in double/float data types. For instance, storing the 0.1 value in double/float (which are binary floating point values) variable we get only an approximation of the value. Similarly, the 1/3 value cannot be represented exactly in decimal floating point type. Decimals are much slower than a … WebAlso, read this: Casting a result to float in method returning float changes result Assert.Equals does not cover this case because the principle of least astonishment states that since every other built-in numeric value type in .NET defines .Equals () to perform an equivalent operation of ==, so Double does so as well.
