This annoying message started appearing somewhere between 8.0 and 8.1 as I recall. It is alerting you to a potential problem. The trouble is that it usually is not an actual problem.
The warning is generated when you use a conditional statement (IF, WHILE, REPEAT) with a precise value for a real number as the condition. Such as:
IF x = 0 THEN...
rather than:
IF x > -0.0001 AND x < 0.0001...
As I understand it the actual problems arise when "x" is the result of a calculation, since rounding errors can produce very small inaccuracies which will prevent it from exactly equalling the desired value even though it should.
The trouble is that I (and many others I am sure) often use a named parameter as the condition with a VALUES statement to limit it to the precise values used in the conditional statements. This precludes any actual errors but still generates the pesky warning.
BTW, turn off your caps lock. It's not polite to shout 😉
