Did I overlook something, or is it the computer's processor, *Does anyone have a clue ?*">> Yep Duncan some ole wag by the name of Pythagorus (sp?) did, he called it the comma................... The two root numbers you are working with (110 & 1200) are not divisible by any common number other than 2, 1 being ignored :-). When the products are derived one is an 'even' number and one is an 'odd' number and never the twain shall meet. Working with sqrts doesn't change this reality The closest you will get is by dividing 110 by 1200 and that answer will be .091666666666666666666666666666667..............ain't nothin wrong with your computers fpu............. it just don't know what ole P'tag did! :-) My guess.
