    Basic celestial naviagtion using a scientific calculator
    From: David Smith

    I would like to speed up the checking of calculations in sight reduction exercises by using an electronic calculator. I have never used a scientific calculator before, but they don't look too difficult to master. However the two Casio calculators that I have, the Casio fx-82MS and fx-82w appear to only work in DDDMMSS.
    Is there a way of entering DDDMM.M and getting answers in the same format? If this is not possible, are there any common calculators or iPhone/iPad apps which are useful for sight reduction calculations? As I want to get a good familiarity with the printed Nautical Almanac and sight redution tables, I am not lookiing for anything more sophisticated than basic arithmatic in DDDMM.M format.
    I'd value your advice.
