float.Parse(...).ToString() ? How to change the way it works?

Question

3.50/5 (2 votes)

See more:

How can I use float.Parse to get the text representing the result (after parsing) written in static point form. For example, I have a string like "100000000." (8 zeroes with a point at the end). I want float.Parse("100000000.").ToString() to be "100000000" (remove the point). But in fact, it returns "1E+08".
How can I get what I want? I know the values are the same, but the strings representing them are not.
Thank you so much!

Solution 1

That just happens to be the default display format in the debugger. You can format a floating point number anyway you want:

C#

float x = float.Parse("100000000.");
String Test1 = x.ToString("#");
