decimal place
After the point
A decimal place is a position to the right of the decimal point in a number.
The first decimal place holds tenths, the second hundredths, the third thousandths, and so on.
Precision is often specified by decimal places: Round to two decimal places means keep two digits after the point, as in 3.14.
