Floating point (Definition)

A type of number value.

Availability:

ECMAScript edition - 2

Although a floating-point value may be equal in magnitude to an integer, logically they are different due to the typing of the value. However, typing in JavaScript is weak and a floating point value and an integer value may well compare equal where they might not have in other languages.

If the JavaScript language ever acquires a stronger typing facility, some scripts may fail on this point.
