Can we validate Min and Max Value for a floating Number using RegExp?

Hi I know that we can validate Min and Max Length of a number using Regex. But can we validate Min and Max Value for a floating point number using the same?

Could anyone please just apply Min and Max Value to following Regex:

^(?=.*\d)(?!.*?\.[^.\n]*,)\d*(,\d*,?)*(\.\d*)?$

Above Regex matches a floating number with optional decimal point and commas.

I guess this should help you. This regex will match 0.00 to 100,000,000.00 upto 2 decimal places.

^(:?(?=[1])(10{0,8})|(?=[^0])(\d{1,8})|0)\.[0-9]{1,2}$

But keep in mind that its always best to compare numbers numerically that using regex.

Here is the link to verify it.

Regex is for strings. You try to compare floats. It's just not the right tool. It's worse than eating your soup with a fork. It's like writing on paper with a knife or cutting your hair with a teaspoon.

Look here for a solution with positive integers without thousands separator : Using regular expressions to compare numbers

I leave the task to you to extend that solution to using floats, thousands separator and negative numbers.
