Arithmetic/Truncating

Truncating is a simpler alternative to rounding. Digits to the right of the place required are just dropped — disregarding whether the first digit to the right is higher than 5 in rank or not.

Examples
What is 98.57 truncated to the tenths place?

The 7 in the hundredths place is dropped. The answer is 98.5.

Truncate 33.504 to the units place.

All digits to the right of the units place (3) are dropped. the answer is 33.
