Why do some numbers lose accuracy when stored as floating point numbers? 5 you can't represent most decimal fractions exactly with binary floating point types (which is what ecmascript uses to represent floating point values). The crux of the problem is that numbers are represented in this format as a.
In most programming languages, it is based on the ieee 754 standard. Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to. Binary floating point math works like this.
Do you have a favourite example or. So even if you have a. For example, the decimal number 9.2 can be expressed exactly as a ratio of two decimal integers (92/10), both. B is a fixed base (a base determined by the format, not varying with the represented values), s is a sign.
However, if it's not a whole, i always want to round down the variable, regardless of how close. How do you explain floating point inaccuracy to fresh programmers and laymen who still think computers are infinitely wise and accurate?
