如何在cmd中计算小数 [英] How Do Calculation of decimal numbers in cmd

问题描述

我有批处理文件，当用户写数字时，会自动将数字加在一起而Cmd无法计算.

I have batch file and When user Writes number,Then automatically Adds numbers together And Cmd Can not calculate.

有什么主意吗?

推荐答案

这是批处理/vbscript混合.
批处理传递参数并解析结果并将其存储在变量Result

Here is batch/vbscript hybrid.
The batch passes the arguments and parses the result and stores it in the variable Result

::'@echo off &for /f "delims=" %%a in ('cscript //nologo //e:vbscript "%~f0" "%*"') do set "Result=%%a"
::'echo(Result=%Result%&exit /b
Wscript.echo Eval(Wscript.Arguments(0))
wscript.quit

::'之后有一个不可见的字符(我希望它们会被转移)

There is one invisible char following the ::' (I hope they get transferred)

一些示例，其中批处理文件存储为Math.cmd(我的语言环境设置为小数逗号)

Some examples where the batch file is stored as Math.cmd (my locale setting has a decimal comma)

>Math 3.76 + 2.54
Result=6,3

>Math 3.76 - 2.54
Result=1,22

>Math 3.76 * 2.54
Result=9,5504

>Math 3.76 / 2.54
Result=1,48031496062992
