# Make Precise Calculations in CMD / Batch - Floating Point Decimal numbers | AC Function 1.0 - By Michał Bukowski

In the traditional CMD environment - Users can do very limited activities with the default commands from

**Microsoft**. But, Using the 3rd party**Plugins / Extensions**created by awesome Batch programmers across the world - we can make almost anything Possible in this dumb**Black Screen.**The Fact is verified and proved with the creation of**BatchStore v.1.0 - By Kvc -**Which uses 50+ Batch Plugins to Acquire a**GUI Output**in CMD console. And, Today - We are again going to talk about another mile-stone in the field of Batch Programming.Complex Calculations in CMD |

Here, in this article we gonna talk about the Great creation of

**Michał Bukowski.**Which allows us to simply calculate the complex and high precision calculation within the**CMD**Console. Although, We (**TheBATeam**) tried to make such function - a long time ago. but, Due to lack of time and planning - it was only limited to version**1.1 of Float function**. But, As we already know...Need is the Mother of Invention!

When

**Michal**needed such utility in their Batch program. They just simply made it using an additional 3rd party plugin. But, All we are focused on is -**Results**. How they are achieved is a different story - that is not we are concerned about much. So, Without wasting any time - Let's know more about the great creation and its usage. So, You can use it in your own programs. :)## Make Precise Calculations in CMD / Batch | AC Function 1.0

If you are families with

**CMD's***Set*Command - Then You will know that it only allows the normal mathematical operations on the integer data types. Which means, you can't do calculations in float / Decimal point numbers. Which limits**Batch programming**in many professional areas. And,**AC Function By Michal**is a little step towards removing that limitation from**CMD.**

##
**What is AC Function?**

It is a Simple

**5.06 KBs**of Batch Function - which uses,**BC.exe**Batch Plugin to manipulate the input and gives the required result as output. The Function converts the Simple mathematical expressions by users into the Format that**BC.exe**understands. And, takes the Output from the plugin to return the answer to the user. So, in a way -**AC Function**acts as a great intermediate between the user and the complex bc.exe plugin.## Features of AC Function By Michal: (From 💚 of Author)

As, Per the words from the author of the Function - Batch's built-in

**SET /A**calculator works only with integers. Its very limited tool, what is not enough for**professional batch programming**. By the way, your FLOAT plugin does not work with some calculations.- Calculates even complex calculations (like:
**"2*9/(11.5-9.11*2)+(2*7)"**) - Writes results into variables directly...
- Rounds the entered numbers (also with calculations - two in one string!) with chosen number of decimals (Example:
**2.912 to 3 or 8.14009 to 8.15**) - Works with negative numbers.

Currently, in version 1.0 of the function - it supports almost the basic functionalities like -

**addition (+) WORKS,****subtraction (-) WORKS****multiplication (*) WORKS****division (/) WORKS****exponentiation (^) DOESNT WORK (by now)**

But, The other functionalities like -etc. will be added in next versions. Hope, They'll come out Soon. And, till then - You can*Exponential, log***Download AC Function**ver.1.0 in your programs.

## How to Use?

The

**AC Function**allows you to perform*3 Operations*on the expressions / numbers you'll provide to it. You can either**make calculations**of an expression - Or you can**Round off**a number upto a specific given precision. And, the**3rd Operation**is the mixture of above two operations. You can calculate and round off the result in one step.### Syntax of AC Function:

Calculation Usage:

CALL AC.BAT C [CALCULATIONS] [OUTPUT VARIABLE]

Ex.call ac.bat c (1/7)*3.5/(11+7) var1

( OUTPUT: VAR1=0.02777777777777777777 )

Rounding Usage:

CALL AC.BAT R [VALUE] [DECIMALS] [OUTPUT VARIABLE]

Ex. call ac.bat r 0.02777777777777777777 4 var2

( OUTPUT: VAR2=0.0278 )

Calculation + Rounding Usage:

CALL AC.BAT C [CALCULATIONS] [OUTPUT VARIABLE] R [DECIMALS]

Ex. call ac.bat c (1/7)*3.5/(11+7) var4 r 4

( OUTPUT: VAR4=0.0278 )

And, That is all you need to know about this great function. You just need to

the PI value is not correct in the above image.

ReplyDeleteRounding it may be a good idea.

Delete:) Glad to have you both here. :) You both are right! As, this Image will explain most of my talk.

Deletebecause, I've used

355/113Fraction for calculating that value. You can get the project files either from github or from mediafire. (Any platform you trust) :) And, providing better fraction to the function will give more precise value of Pi. :)I will say, it's not the function's fault - It's the User's Fault to have the less precise value. :)
