Division in JavaScript

Is all division in JavaScript floating-point division? I'm coming to this from a Java and C# background.

Java and C# are similar to each other in many ways, but JavaScript is rather different from both of them. You'll do well to avoid making assumptions about JavaScript based on what either of those languages do.

The default JavaScript Number type is double-precision 64-bit binary format IEEE 754 value, though there are some other types that can be explicitly declared. What an operator does is based on the type(s) it is acting on, so for default numbers division is double-precision floating point.
