This is question 11 from the regex101 quiz
I have been trying to figure out a solution to solve the test case below from failing. Can someone help with this?
Test 60/89: Just a dot is not a valid floating number.
I am using the regex below.
/^[+-]?\d*([.,]\d*)?([Ee][+-]?\d+)?$/g
You can use
/^[-+]?(\d+[,.]|\d*[.,]?\d+)(e[-+]?\d+)?$/i
Details:
^ - start of string[-+]? - an optional - or +(\d+[,.]|\d*[.,]?\d+) - either one or more digits, then , or ., or zero or more digits, an optional .or,` and then one or more digits(e[-+]?\d+)? - an optional occurrence of e, then an optional - or + and then one or more digits$ - end of string.
