Can an HP 48GX add fractions? Rather than always converting the factions to decimals, is there a program where you can enter in numbers to the 1/16ths of an inch and add the fractions. This is a common feature on construction calculators and would be very nice on a 48GX. I'm ordering one this week and am possibly ordering an 12C for adding fractions, it just seems that the 48GX should be able to handle this.

Thanks.
