Remove decimal point from a decimal number

Question

I am trying to remove just the decimal point from a decimal number in C#.

For example:

• My decimal number is 2353.61 I want 235361 as the result.
• My decimal number is 196.06 I want 19606 as the result.

How can I do that?

Answer 1

I would simply get the number of decimals and multiply it by the correct power of 10. Probably not really a concern but this also would be faster and use less memory then casting it to a string splitting / recombining it, then casting it back to a double. This also works for any number of decimal places.

decimal d = 2353.61M;
int count = BitConverter.GetBytes(decimal.GetBits(d)[3])[2];
d *= Convert.ToDecimal(Math.Pow(10, count));

Using this answer to get the number of decimals.

Answer 2

If you always want the printed value to include 2 digits for consistency, you can just multiple by 100 and truncate the result.

value = Math.Truncate(value * 100m);

This would provide the value you specified in both cases, but also provide a similar result for 2353.6 (-> 235360).
