    114114=== Value representation in Json
    115115
    116 Internally BigDecimal is used for computing and storing issue values, utilities etc. Doubles always give rounding problems and can not be assumed to sum properly to 1 and therefore are not used.

    118118Since JSON parses normal number directly into doubles, it is necessary to place numbers also inside string objects ("..."). That in turn forces us to put some hard marker in the string to see if "1" would be a discrete value or number value. To do this, any Value contained in a string that is of the form "=X.Y" where X is a positive or negative integer and Y a positive integer is a NumberValue. Anything else is interpreted as a DiscreteValue.
