This article is about how to use batch processing to multiply the value of the last column of text by a number. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

A.txt

1##4072.0###52.19### # 72## #

2#38705.8# 51.73## # 70# #

372###389.0##51.80##19.77# # 72#

4##59.71#3715.45##71#

With # and space as delimiters, the value of the last column is multiplied by 7, and everything else remains the same.

Under the known condition, the number is random, and the value of the last column is an integer, even if multiplied by 7, it is still within the range that CMD can calculate.

# and spaces and "." The location and number of and the number of columns per row are random.

The output is as follows:

1##4072.0###52.19### # 504## #

2#38705.8# 51.73## # 490# #

372###389.0##51.80##19.77# # 504#

4##59.71#3715.45##497#

Just operate on the values of the last column, and everything else remains the same.

It is required to be universal and efficient.
