各位老大,如何从下面的test.txt中第一列和第二列相乘把得数写入y.txt


我的p显示"运算符不存在"why?
我的p:
@echo off &setlocal enabledelayedexpansion
for /f " tokens=1* delims=, " %%a in (test.txt) do (
set /a money=%%a*%%b
echo !money!>>y.txt
)

pause

　　根据所列被乘数的特点，可以先忽略小数点，最后移位小数点即可：

@Echo off&SetLocal EnableDelayedExpansion

for /f "tokens=1-3 delims=. " %%a in (test.txt) do (
	set /a menoy=%%a%%b*%%c
	set menoy=!menoy:~0,-3!.!menoy:~-3!
	echo/!menoy!>>new.txt
)
pause&start new.txt

谢谢,我用excel了,合计归总比P快,但是还是得谢谢你给的思路!!!

gawk "{print $1*$2}" test.txt|more>y.txt

谢谢,感谢非常,gawk的用法我搜搜先
