The decimal point is handled by implication. Consider all things
to be integer. So

1.23 + 1.23 = 2.46 --we have an implied 2 decimal places

1/2 = 1 or 1.5  --depends on the size of the result field

BCD and COBOL hence go well together with declarations
like "####.##"

From distant memory the IBM size of these declarations is
limited to about 18 digits (which covers most financial
apps).

I couldn't find on wikipedia mention of how the decimal point is
handled, just the sign. Anybody know?
