Visual studio intellisense window for numeric literal?

when we press . (dot) key after any character and string literal visual studio open intellisense window but not for numeric literal. I want to why visual st开发者_如何转开发udio don't do that for numeric? what the technical reason is behind this.

Because 8.9 is a number, and to get there you type 8 + ., thus 8. could become a number.

Intellisense on decimal numbers could get annoying really quickly.
