TRUNC Formula Syntax

=TRUNC(3.14159, 2)

Example Use Case

Truncating a number to a specified decimal place for precise trimming

Understanding the TRUNC Formula

The TRUNC function in Excel cuts a number to a specified number of decimal places, discarding the rest without rounding. It’s a precision tool for trimming numbers, similar to INT but with decimal flexibility, ideal for data cleanup or exact numeric cuts.

TRUNC(3.14159, 2) returns 3.14, chopping off 0.00159. It takes two arguments: the number and digits (defaulting to 0 if omitted), offering a straightforward way to shorten values—unlike ROUND, it never adjusts up or down based on value.

Why Use TRUNC?

TRUNC ensures exactness—think preparing data for display, financial calculations, or stripping excess decimals. Its no-rounding approach guarantees consistency, making it a reliable choice when you need raw truncation without bias.
