And what do you expect the resulting value would be?

Solution 2

you could consider that if you remove the '.'s, maybe using string.Replace(".","") then, each position represents thousands, hundreds, tens and units - then convert the string with the '.'s remove to an integer - no pun intended, but Im not sure what value that really gives you, storing it as a number

Exactly! A number would only hold one decimal place in double, float or decimal format. Removing 3 or (total number of periods - 1) would resolve this error. See Solution 1 for this.

No (existing) number format can accept it. Floating point numbers would also allow only one decimal point. Your number contains 4.

Remove the . from your string, and then convert it. Or atleast allow only 1 decimal point in your string.

If you're having one decimal point, you can still convert it to Double[^], Float[^] etc numbers. Even if you have one decimal point, you will have to convert it to decimal or float, conversion to an integer with a single decimal point would cause the error.

There is a better way of converting the strings to integers and getting to know whether they can be converted or not, using a TryParse[^] in your code, which would either return a true if number was converted or a false if there were any errors in the format.

Remember the size of the data type

Even if you convert the string to a numeric data type, the result would be based on the size of the data type. You need to consider the size of the data type you're going to use.
