· 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 … · 5 You can't represent most decimal fractions exactly with binary floating point types (which is what ECMAScript uses to represent floating point values). So there isn't an … · 16 Floating-point numbers, also known as real numbers, are used when evaluating expressions that require fractional precision. For example, calculations such as square root, or … · The IEEE floating-point standard attempts to define a single format (or rather set of formats of a few sizes) that can be implemented on a variety of systems. It also defines the … · I want to take a floating-point number and round it down to the nearest integer. However, if it's not a whole, I always want to round down the variable, regardless of how close … · And also, any significant floating point program is likely to have significant integer work too even if it's only calculating indices into arrays, loop counter etc. so even if you have a … · How do you explain floating point inaccuracy to fresh programmers and laymen who still think computers are infinitely wise and accurate? Do you have a favourite example or … · Strictly speaking, it's a binary fraction. It is not an integer. It's not a floating-point number, either (if anything it's fixed-point) and even if it could be floating, our task here is to … · As dasblinkenlight already answered, the numbers come from the way that floating point numbers are represented in IEEE-754, and Andreas has a nice breakdown of the maths. What is the difference between a single precision floating point operation and double precision floating operation? I'm especially interested in practical terms in relation to video game …
