regex to search numbers or float numbers in one pattern

i need a regex to accept both integers or float but not any other characters like for int ex: 28128 and float with two decimal precision ex: 123123.00 or 123213.05 ...

i have for integers and float [separately] like below

var numbers_only = /^[0-9]+$/;
var decimal_only =  /^[0-9]+\.[0-9]+$/;

so how can i merge this into one...so i can accept integers and float(2 decimal places)...

You can always merge multiple patterns using | (OR) operator:

/^([0-9]+|[0-9]+\.[0-9]+)$/

Use an optional group.

^\d+(?:\.\d+)?$

(?:\.\d+)? will match the decimal part if there is any in the input string. ? after the non-capturing group makes that group as optional.

For two decimal places.

^\d+(?:\.\d{2})?$
