This article introduces the formula syntax and usage of the TRUNC function in Microsoft Excel.
TRUNC function function
The TRUNC function is used to cut off the decimal part of a number and return an integer. That is to say, the calculation retains the value after removing the specified number of bits (the result must be equal to or less than the original value).

TRUNC(number,num_digits)
Translated into the vernacular format:
TRUNC(目标单元格,要保留位数)
