C# - Rounding Down to Nearest Integer
C#C# Problem Overview
I have a C# app that is calculating some numbers. I need to round down.
var increment = 1.25;
var result = 50.45 - 23.70; // equals 26.75
int interval = difference / increment; // result is 21.4. However, I just want 21
I have to get the interval to an int. At the same time, I cannot just use Convert.ToInt32 because of its rounding behavior. I always want the lowest whole number. However, I'm not sure how.
C# Solutions
Solution 1 - C#
Just try this..
int interval = Convert.ToInt32(Math.Floor(different/increment));
Solution 2 - C#
You can also just simply cast the result to int. This will truncate the number.
int interval = (int)(difference / increment);
Solution 3 - C#
Use the static Math class:
int interval = (int)Math.Floor(difference/increment);
Math.Floor() will round down to the nearest integer.
Solution 4 - C#
The Math.Floor() function should do the trick:
int interval = (int)Math.Floor(difference / increment);

Solution 5 - C#
Convert.ToSingle();
is another method
