Issue with Regex in isNumber.js

[vijaykumarpendem]

The regex written is /[0-9]+/
It would return true even if there are any other characters in the string.
If the regex is /^[0-9]+$/, it specifies there should not be any characters other than numbers.
Please look into this.

/^[0-9]+$/ this will only work for numbers not floating point values. But if you want to include a decimal point in your string then you should use this regex : /^[0-9]\d*(.\d+)?$/
