EEX key (powers of 10)

Note that the degree and minute entries must be integers, and the minute and second entries must be positive. Decimals are not allowed, except in the seconds.

Note too that the HP Prime treats a value in hexgesimal format as a single entity. Hence any operation performed on a hexagesimal value is performed on the entire value. For example, if

you enter 10°25′ 26″ 2, the whole value is squared, not just the seconds component. The result in this case is 108°39′ 26.8544″ .

Numbers like 5 × 104 and 3.21 × 10–7are expressed in scientific notation, that is, in terms of powers of ten. This is simpler to work with than 50 000 or 0.000 000 321. To enter numbers like these, use the Bfunctionality. This is easier than using s10k.

Example: Suppose you want to calculate

(4 × 10–13)(6 × 1023)

---------------------------------------------------

3 × 10–5
