RE: Casio fx -5000F - Exponents
xn does only accept positive integers, no negatives. the main difference to xy, which accepts any numbers, is the designation on the display:
if you type 123 [xy] 456 it shows up on the calc as 123xy456, which calculates 123^456. so, xy is kind of similar to our well-known yx - 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. |
