Converting String To Float in C#


I am converting a string like "41.00027357629127", and I am using;




These methods return 4.10002732E+15.

When I convert to float I want "41.00027357629127". This string should be the same...

The Best Answer is


Your thread's locale is set to one in which the decimal mark is "," instead of ".".

Try using this:

float.Parse("41.00027357629127", CultureInfo.InvariantCulture.NumberFormat);

Note, however, that a float cannot hold that many digits of precision. You would have to use double or Decimal to do so.

First, it is just a presentation of the float number you see in the debugger. The real value is approximately exact (as much as it's possible).

Note: Use always CultureInfo information when dealing with floating point numbers versus strings.


This is just an example; choose an appropriate culture for your case.
