WebJan 20, 2015 · Floating point values contain limited precision, which results in their being unable to exactly represent some values, and for errors to accumulate with repeated computation. As a result, it is common advice to only use an equality comparison in very specific situations. WebSep 23, 2024 · Equality comparisons of floating-point values ( double and float) are problematic because of the imprecision of floating-point arithmetic on binary computers. … small it consulting firms vancouver
Code Inspection: Equality comparison of floating point …
WebNov 5, 2024 · Floating-point numbers should never be directly compared for equality, because the IEEE floating-point representation does not support an exact equality operation. Two numbers that you can easily verify to be equal by inspecting the code might actually have different bit representations. Overloaded and Generic Operators WebJul 30, 2024 · The floating point comparison is not similar to the integer comparison. To compare two floating point values, we have to consider the precision in to the comparison. For example, if two numbers are 3.1428 and 3.1415, then they are same up to the precision 0.01, but after that, like 0.001 they are not same. WebOct 16, 2008 · As a consequence, an assertion might fail when checking for equality of two floating-point quantities even if the program is implemented correctly.
