There is no hint to the truemanufacturer of this OEM-calculator.Running Mike Sebastian's "Calculatorforensics" reveals the Canon F-720 as one of the"new-generation" calculators using binary arithmetic instead of thecommon BCD (Binary Coded Decimal) arithmetic to perform internal calculations.According to the manual this calculator uses up to 24 digits of precision and weget indeed the unbelievable result of 9.00000000005281641187...running the forensics test.
