✅ System.FormatException

Me and another are writing a RPN calculator.
I get this error message when trying to calculate

3 4.8 5.7 + * 2.5 *

3 4.8 5.7 + * 2.5 *

3 4.8 5.7 + * 2.5 *

3 4.8 5.7 + * 2.5 * but when he runs it he does not get an exception on it. We have the exact same files and code. Why?

Your PC is probably set to a language that uses a comma as a decimal separator, not a period

Try inputting the same string, but with commas

Also, I recommend using TryParse()TryParse() instead of the ConvertConvert class, it lets you check if a number is valid without throwing exceptions

If you want to continue using periods for separators, you can set the culture of the thread to InvatiantCultureInvatiantCulture, or pass CultureInfo.InvariantCultureCultureInfo.InvariantCulture as a second parameter to your convert method

Or to TryParse()TryParse()

Could this issue be resolved by using

Double

Double

instead?
