RegEx - Exclude zero

Question

How can I exclude the 0 input in this regex? The user should be able to enter any number... but not the zero

^([0-9]*|\\d*\\.\\d{1}?\\d*)$

Than

Answer 1

What about this:

^((?:[1-9][0-9]*)(?:\.[0-9]+)?)$

Match:

1
5
10
22
5000
1.0
10.10
123.456

No match:

0
00
007
0.0
0.000
0.50
0.01
5,432.10
1,234,567
10.

You could further lock it down to specific ranges, as explained here:
