Re: Number registers and prices: digits after decimal point

Are you aware that number registers are integers and you wish to always
append ‘.00’ because you only invoice whole Euros?

Are you doing arithmetic on the number registers?  Or could the amounts
be stored in string registers instead.

Do you want these number register values to be interpolated in content
which is to be preprocessed by something like tbl(1) or pic(1)?  If so,
which preprocessors.

It's looking like a macro which produces the string you require may be
useful so something like

    .ds t 3141592.65
    Total \*[money \*t]

uses the macro ‘money’ to produce output as if

    Total 3 141 592,65

was entered.
