Bug in HP 300s+: FACT on powers > 9
The HP 300s+ has a FACT button which finds the prime factors of integers. For example, if you enter 10! and press = then press FACT, it displays 2^8 × 3^4 × 5^2 × 7. But FACT has a bug in it: The powers are always displayed in hex! (This is noticeable when the power is > 9, of course).
Examples: 2^15 = FACT > 2^f 2^16 = FACT > 2^10 2^33 = FACT > 2^21 12! = FACT > 2^a × 3^5 ... etc. Although the HP 300s+ is often characterized as a rebranded Casio, I am unaware of any Casio model that has this bug. Note: FACT only returns prime factors <1000. This is not a bug, but a documented function limitation, shared with Casio. <0ɸ0> Joe
