Float equals c#

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 … WebTests whether the specified floats are equal and throws an exception if they are not equal.

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. WebJul 6, 2011 · If you go through a lot of floating point operations which in "infinite precision" might result in 0, you could end up with a result "very close" to 0.
