## Rounding Numbers (Interactive Mathematics Lesson)

Use this interactive widget to see how the different methods of rounding numbers affect your number.
• Step 1. Click on the number below to select which number to round.
• Step 2. Select the method of rounding from the list below.
• (Remember that the different methods for rounding often give the same results. Therefore, your number will not always change.)

Select the method for rounding:

 Round Half Up Round Half Down Round to Floor Round to Ceiling Round Half Away from 0 Round Half Towards 0 Round Half to Even Round Half to Odd Round Half Randomly

## This is the Round Half Up Method

Here are some simple examples of the Round Half Up method:
 Examples 2.6 2.5 2.4 -2.4 -2.5 -2.6 "Round Half Up" becomes 3 becomes 3 becomes 2 becomes -2 becomes -2 becomes -3 "Round Half Down" becomes 3 becomes 2 becomes 2 becomes -2 becomes -3 becomes -3 "Round to Floor" becomes 2 becomes 2 becomes 2 becomes -3 becomes -3 becomes -3 "Round to Ceiling" becomes 3 becomes 3 becomes 3 becomes -2 becomes -2 becomes -2 "Round Half Away from 0" becomes 3 becomes 3 becomes 2 becomes -2 becomes -3 becomes -3 "Round Half Towards 0" becomes 3 becomes 2 becomes 2 becomes -2 becomes -2 becomes -3 "Round Half to Even" becomes 3 becomes 2 becomes 2 becomes -2 becomes -2 becomes -3 "Round Half to Odd" becomes 3 becomes 3 becomes 2 becomes -2 becomes -3 becomes -3 "Round Half Randomly" becomes 3 becomes 2 or 3 becomes 2 becomes -2 becomes -2 or -3 becomes -3
