Round final payoff to 50 cents or 1 dollar

#1 by PimPim

Dear all,

I would like to round the final payoff (in currency unit) to 50 cents or 1 dollar, but cannot find any in the document. For example payoff = $24.2 would be $24.5.

Could you please let me know your suggestions?

Thank you very much.
Kind regards,

Have you considered using

    from math import ceil
    def roundup(x, u=0.5):
        return ceil(x/u)*u
    # example:

Dear gr0ssmann,

Thank you very much. It works! However, we cannot have the rounded payoff shown in the Payments tab, right?

Kind regards,

I believe oTree currency values must be whole numbers. Not so sure though. (This is one of the most difficult and perplexing issues in oTree.)

Currency rounding is described in the section "Decimal places" here: https://otree.readthedocs.io/en/latest/currency.html#decimal-places

Is there some specific issue with it?
