Answer 1

The method you found is very good. It supports numbers up to 99,999,999 and is very fast.

There is a simpler way to use SET /A that works with numbers up to 9999. It uses the modulus operation. The method cannot be extended to larger numbers.

 set n=0027
 set /a n=10000%n% %% 10000

The FOR /F method that Dale posted works with "any" size number (up to 8191 digits). However, it needs just a bit more work to handle zero values.

set n=000000000000000000000000000000000000000000000000000027
for /f "tokens=* delims=0" %%N in ("%n%") do set "n=%%N"
if not defined n set "n=0"
