RE: HP30S Scientific Calculator
I've got an HP30S with Version 03! S/N CN0024 (very early?)
1 ab/c 110 > 0/1 :D 2 + 1e9  2 > 1e09 sin 3.14159265358 > 9.793238461e12 sin(3.1415926535+7391741495627E23)*1E171587582 > 3.504446358e01 sin(3.1415926535+7391741495628E23)*1E171587582 > 3.504438966e01 :O Quote:Part of the reason that the HP30S returns the exact answer of 9 for the forensics test is that the HP30S takes the liberty of rounding results to integers that are in very close proximity, which provides answers that are reassuring to novice users.Very likely! Check Citizen SRP280 and SRP285II (other models from the same Kinpo series). The 280 gives approx. 5.2e11 in the forensics test, the 285II (and all later Citizen models) gives 0. Note, SRP285 (without II!) is 14digit decimal, not binary. TI models are also decimal. Quote:Key in 1 [a b/c] 110 to put in 1/110 as a fraction via the [a b/c] key. The result is: 0/1. Or calculate 1/101/11 in fractional form, the result is 0/1Citizen models (280, 285, 285II, 300) and TI34II (also a similar Kinpo model!) do this fine. Maybe it's a specific firmware bug in HP30 v. 03.
