端数を切り捨てる (hasū o kirisuteru)

How it works
This phrase consists of the noun 端数 (hasū, meaning 'fraction' or 'odd amount'), the direct object particle を (o), and the Ichidan compound verb 切り捨てる (kirisuteru, meaning 'to cut off/discard'). It is frequently used in mathematics, accounting, business, and programming to describe the act of truncation or rounding down numbers. It contrasts directly with 端数を切り上げる (to round up) and 端数を四捨五入する (to round to the nearest whole/fraction).
