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

This work only with natural numbers to 5 digit and limit five 0 digit at the left (you can personalize that limit)

/^[0]{0,5}[1-9]\d{0,4}$/

match:

1
01 .. 000001
0100000 .. 0000010000

not match:

0
00 .. 00000

Answer 2

Try this: ^([1-9]+).\d+$ This requires you to enter at least 1 digit from 1-9

Or ^([1-9]).\d$ This does not require you to enter anything but does restrict what you enter as 1-9

Answer 3

The following regex

^(?!0*(\.0+)?$)(\d+|\d*\.\d+)$

Does not match

0
0.0
 .0

But allows

  .1
 0.01
 1.00
 1.1
01.01
10.10
 1

Answer 4

If I understand your requirement, use [1-9] in place of [0-9] or \d:

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

Answer 5

You just need to change the: * [0-9] for [1-9] * /d for [1-9]

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

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

\d is [0-9]

Answer 6

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:
