C# Double - ToString() formatting with two decimal places but no rounding

I'm using float numbers and I want to get the number of decimal points without any rounding-off being performed.

For Eg. float x = 12.6789 If I want upto 2 decimal points, then I should get (x = 12.67) and NOT (x = 12.68) which happens when rounding takes place.

Plz suggest which is the best way to do this.

Answer 1

You should be able to use Math.Truncate() for this:

decimal x = 12.6789m;
x = Math.Truncate(x * 100) / 100; //This will output 12.67

Answer 2

You can achieve this by casting:

float x = 12.6789;
float result = ((int)(x * 100.0)) / 100.0;
