Floating point calculations?

I’m trying to perform a simple calculation in a batch file but I’m having difficulties.

Here is what I’m working with:

set /a Factor= 480 / (%SOURCE_VIDWIDTH%000)
set “Scale_Factor=%Factor:~0,-3%.%Factor:~-3%”
set /a Output_Height= %Scale_Factor% * %SOURCE_VIDHEIGHT%
set /a Border_Value= (320 – %Output_Height%) / 2

Echo.
Echo.
Echo Spline64Resize(480,%Output_Height%)
Echo AddBorders(0,%Border_Value%,0,%Border_Value%)
Echo.
Echo.[/CODE]

In the example that I’m working with:

SOURCE_VIDWIDTH=1280
SOURCE_VIDHEIGHT=720

Spline64Resize(480,0)
AssumeFPS(0,160,0,160)[CODE]set /a Factor= 480 / (%SOURCE_VIDWIDTH%000)
set “Scale_Factor=%Factor:~0,-3%.%Factor:~-3%”
set /a Output_Height= %Scale_Factor% * %SOURCE_VIDHEIGHT%
set /a Border_Value= (320 – %Output_Height%) / 2

Echo.
Echo.
Echo Spline64Resize(480,%Output_Height%)
Echo AddBorders(0,%Border_Value%,0,%Border_Value%)
Echo.
Echo.[/CODE]

In the example that I’m working with:

SOURCE_VIDWIDTH=1280
SOURCE_VIDHEIGHT=720

Spline64Resize(480,0)
AssumeFPS(0,160,0,160)
