This is a monetary type and as it is impossible to squeeze infinitely many Real numbers into a finite number of bits, we represent monetary types as integer numbers of cents/pence to reduce potential rounding errors. So $10.35 becomes 1035. Don’t forget to divide by 100 (or the relevant minor unit denomination) when presenting information to a user. The relevant minor unit denomination should be determined from the currency’s corresponding ‘E’ value.
