Yes, exactly. > Also, '-1' is > valid as precision, but to set arbitrary valid precision one > would have to use code like > > if prec = -1 then > outputFixed() > else > outputFixed(prec::NonNegativeInteger) Yes, and as -1 is not documented and only "settable" via output* without arguments I guess you are thinking about an Integer argument to set the precision, am I right? > And to set desired mode we would need chain of tests.

I agree that it could be handy, and, even, an error message can be displayed, in case of a typo for example, that helps the user in the interpreter for the different mode available (no full explanation of course). It just remains from my point of view the previous spacing setting as suggested in the previous diff. > which sets desired mode.
