Rounding gives a simpler number near the real one. Let's round 1.237 to the nearest hundredth. It's between 1.23 and 1.24.
On the line, 1.237 is past the halfway mark, 1.235. So it's closer to 1.24.
Here's the same idea with digits. Look at the thousandths digit. 5 or more rounds up, and 4 or less stays.
So 3.142 rounds to 3.14, and 3.145 rounds to 3.15, because halfway rounds up.
