Convert string to float in C #

Question

I convert the string as "41.00027357629127" and I use;

Convert.ToSingle("41.00027357629127"); 

or

 float.Parse("41.00027357629127"); 

These methods return 4.10002732E + 15.

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

Answer 1

Your default locale is set to a decimal place with a,, instead of a..

Try using this:

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

Note, however, that a float cannot hold as many precision digits. For this you will have to use double or Decimal.

Answer 2

Firstly, it’s just a presentation of the float number that you see in the debugger. The actual value is approximately as accurate (as possible).

Note. Always use CultureInfo when dealing with floating point numbers versus strings.

 float.Parse("41.00027357629127", System.Globalization.CultureInfo.InvariantCulture); 

This is just an example; Choose the right culture for your occasion.

Answer 3

Use Convert.ToDouble("41.00027357629127");

Convert.ToDouble documentation

Answer 4

You can use "float asd = (float) Convert.ToDouble("41.00027357629127");

Answer 5

Float accuracy is 7 digits. If you want to save the whole batch, you need to use double , which stores 15-16 digits. Regarding formatting, look at the message about formatting doubling . And you need to worry about decimal separators in C # .

Answer 6

You can double.Parse("41.00027357629127");

Answer 7

You can use parsing with double instead of float to get a more accurate value.
