Converting String To Float in C#

Question

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

Convert.ToSingle(\"41.00027357629127\");

or

float.Pars         


        

Answer 1

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.

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

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

Answer 2

You can double.Parse("41.00027357629127");

Answer 3

Use Convert.ToDouble("41.00027357629127");

Convert.ToDouble documentation

Answer 4

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

Answer 5

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.

Answer 6

You can use the following:

float asd = (float) Convert.ToDouble("41.00027357629127");
