>> IIF(L<38.78,X,Y)
the code will yield X when in fact it should yield Y because the low is
not less than 38.78 (it is exactly 38.78). This occurs simply because of
the imprecise representation of the value in AB.
Does anyone know how to get around this, and if its normal for the value
to be imprecise in AB? <<
Comparing floating point numbers can be a problem if you are not
careful. Fortunately financial price data is quantized so this problem
is easy to work around. I your case, lets say the next legal price below
38.78 is 38.77. You can use any number between 38.78 and 38.77 for your
test. L<38.779 will work because it is below the computers
representation of 38.78 but above 38.77. Also L<38.778 will work so will
L<38.777, etc.
