Negative floats are not matched correctly.

[haynesgt]

In negative floats like -2.5 and -2.004E7, the decimal is not highlighted as part of the number. This is because there is no word boundary before '-', but a word boundary is expected. Here is a suggested fix, where the typescriptFloat pattern expects a word boundary after '-' instead of before it.

Thanks for the patch! I'll get that applied.
