Looks like I missed some cases when I looked at numeric constants. I'll take another pass.

Some more examples,

1Dkb
1.Dkb
1.E12kb
1.1Dkb
1.1E12kb
.1E+12Dkb
1Lkb
1.5Lpb
1.E12Lkb
1.14E12Lkb
.14Ltb
1E12Lkb

I think there are a couple more scenario's included here, such as decimal numbers without a leading digit before the decimal point.

I have these worked out in PR #156, I merged the regex in to 3 primary patterns, integer, hex, and decimal, but did not scope them by their final storage type. I have eliminated the patterns that are not allowed (they haven't implemented binary or allowing underscore separators). I could separate these changes out to a new PR.
