Not sure if it helps, but doubles and floats are infamous for this kind of
thing. The select tag does an equality comparison, and floats and especially
doubles are a little imprecise so that fails. This is also why an equality
test on a float/double is taught as "Math.abd(d1-d2) < 0.00000000001" or
similar instead of "d1 == d2" / "d1.equals(d2)".
In your situation, I'd convert the monetary value of the option's strike
price to a fixed point number (using a BigDecimal with a scale of 2, 3 or
maybe 5) or even an integer number (the BigDecimal multiplied by 100, 1000 or
100000).
