Convert decimal value to exponential value

[Pankaj Saha]

Hi, I have a decimal number. I need to convert this decimal value to exponential value. I have a vb.net code to convert from decimal to exponential value is Format(100000, #.0#E-##) . When I run this code in vb.net it returns 1.0E5 I need the same expression for the c#. I am using the following code String.Format("{0:E}", 100000) and its returns 1.000000E+005, but I need 1.0E5. The same for the another value String.Format("{0:E}", 0.000597), I need 5.97E-4 but it is returning 5.970000E-004. Does anyone let me know the right expression :confused:

Use string.Format("{0:0.0E+00}", 1000000);.

Thanks for your replay. When I run**

string.Format("{0:0.0E+00}", 0.000597);

**its return 6E-04 but I need 5.97E-4. I do not want to round the number.

I have done some small changed in the expression and got the near of correct result

string.Format("{0:0.0E2}", 0.000597);

then its returns 5.97E-004. Can we remove 00 after the E ?

Got one solution

string.Format("{0:#.0#E-00}", 1000000);
