round down
【动】下舍入，舍去
1. To round, making no adjustment to the part of the numeral that is retained. If a numeral is rounded down, its absolute value is not increased. Rounding down is a form of truncation, e.g., the numerals 12.6374 and 15.0625, when rounded down to two decimal places, become 12.63 and 15.06 respectively.
对数字的保留部分不作调整的舍入。如果一个数字被下舍入，其绝对值不会增大。下舍入是截断的一种形式，例 如数字12.6374与15.0625，当下舍入到二位数字时，将分别变为12.63到15.06。
2. On a calculator, the elimination in the result of the calculation of all digits beyond the least significant digit.
