Integer operations are okay, but decimal point operations are not. For example: set /a BB=90.6 displays 0, and methods like set /a BB=9(0.6) don't work either. I searched the forum and didn't find related issues. Please give your advice!

The computing power of CMD is indeed relatively weak: it does not directly support the addition, subtraction, multiplication and division of decimals.

So, is there a way to implement decimal multiplication operations through the VBS script method?

The answer is given on the 2nd floor.

If it's VBS, it's too simple. It's just that the output format has some problems when the number of digits is too long. I don't know how to get rid of that scientific notation.

Simulating manual operations can solve... multiplication, addition, and subtraction of large numbers... I still don't know how to write division.
