Casio fx -5000F - Exponents

[damaltor]

xⁿ does only accept positive integers, no negatives. the main difference to x^y, which accepts any numbers, is the designation on the display:

if you type 123 [x^y] 456 it shows up on the calc as 123x^y456, which calculates 123^456. so, x^y is kind of similar to our well-known y^x - it raises one number to the power of the second number.

the xⁿ key is more like a shift key. if you want the same result, you have to press 123 [xⁿ] 4 [xⁿ] 5 [xⁿ] 6 (note the second and the third xⁿ). This will be shown on the display as 123⁴⁵⁶ (with a tiny 4, 5 and 6, but without a special character for the xⁿ key.

This can reduce the memory needed for stored formulas by one byte, and it looks nice - still it is of little use as far as i think.
