Changed scalar resources to use fixed-point internally. Scalar resource values are represented using floating point. As a result, users could see unexpected results when accepting offers and making reservations for fractional resources: values like "0.1" cannot be precisely represented using standard floating point, and the resource values returned to frameworks might contain an unpredictable amount of roundoff error. This commit adjusts the master to use fixed-point when doing internal computations on scalar resource values. The fixed-point format only supports three decimal digits of precision: that is, fractional resource values like "0.001" will be supported, but "0.0001" will not be.
