Floating Point Arithmetic

Working around the limitations of the command processor.

Description:

Floating point arithmetic can be achieved by moving the fractions into the integer. I.e. A floating point equitation using values with 3 digits after the dot can be calculated as follows:

Floating Point: 12.055 + 1.001 = 13.056
Integer:        12055 + 1001 = 13056

Script:

1. 2. set /a y=12055 + 1001 echo.y = %y%

Script Output:

DOS

Script Output

y = 13056
