All variables are initialized with a default value of zero unless otherwise
specified. Thus, the use of the variable as a denominator presents a
potential divide by zero or floating point error. In order to prevent the
possibility of the error occurring you will need to condition the formula
prior to division. For example:
if x <> 0 then
y = high / x ;

Subject: Re: Brain teasers (are these known TradeStation bugs?)
I've had a number of manifestations (infestations??) of this error message.
For example, a pair of EL statement such as
x=4;
y=high/x;
might give a floating point error, but changing the code to
y=high*0.25;
will clear it up. The problem only occurs intermittently and I've never
gotten a helpful answer from the TS folks. So I've just kluged my way around
it after a lot of trial and error. And yes, I've checked to make sure that
the variables have the correct type declarations.
