How to validate decimal no using ng-pattern in angularJs?

Question

I want to validate decimal no like 0.5,0.05 and also natural no.

For natural no I used this pattern /^[0-9]{1,7}$/.

What pattern I will use for decimal no and natural no together?

Answer 1

Use this /^-?[0-9]\d*(\.\d*)?$/

Answer 2

I think this should work. /^[0-9]{1,7}(\.[0-9]+)?$/
