Hi Bruno,

This works as expected with the little addendum that @# in Calc seems to ignore the header line (not present in this example), but the Lispy syntax doesn't. So the 1 in the "if" becomes a 2. > Note that, for Calc, 'X:Y' means the fraction 'X/Y' of the two > integers X and Y: > > 40:01 = 40/1 = 40 > 40:02 = 40/2 = 20 > 40:03 = 40/3 > 40:04 = 40/4 = 10 This also explains why 40:00 errors out :) Thanks a lot Chris
