How do you round to the nearest tenth (one decimal place)?

Look at the hundredths digit (second decimal place). If it is 5 or higher, increase the tenths digit by 1. If less than 5, keep the tenths digit (e.g., 3.46 rounds to 3.5; 3.42 rounds to 3.4).

How do you round to the nearest hundredth (two decimal places)?

Look at the thousandths digit (third decimal place). If 5 or higher, round up (e.g., $12.876 rounds to $12.88; $12.874 rounds to $12.87).

What is Banker's Rounding (Round Half to Even)?

Banker's rounding rounds half-way values (ending in 5) to the nearest even number (e.g., 2.5 rounds to 2, 3.5 rounds to 4) to eliminate statistical upward bias across large datasets.

How do you round to significant figures?

Count significant figures starting from the first non-zero digit on the left, then apply standard rounding rules to the final significant position.

What is the difference between truncate and round down?

Truncating simply drops trailing decimal places without evaluating digits. Rounding down (floor) always chooses the nearest smaller integer or precision unit.

What is Round Half to Even (Banker's Rounding)?

Banker's Rounding rounds values ending in exactly .5 to the nearest even integer, preventing upward statistical bias across large financial datasets.

What Are the Standard Rounding Rules for Decimals?

The standard rounding rule (round half up) states: look at the digit immediately to the right of the target rounding place. If that digit is 5 or greater (5, 6, 7, 8, 9), round the target digit up by 1. If it is 4 or less (0, 1, 2, 3, 4), keep the target digit unchanged (round down).
