Number

Essentials
A number is simply any number. It is not limited to integers, you may have numbers that have floating points as well.

Extra
Here is a common programming issue.

Lua thinks .1 + .2 doesn't equal .3! Why? This issue has its roots in the IEEE-754 standard for floating decimal point arithmetic. Most programming languages implements this standard (including C in which Lua was written in). Therefore Lua inherits this behavior.
