Leap Year Test

[StephenG1CMZ]

I earlier remarked that I regarded DDAYS as more complicated than the other solutions, assuming that working out the number of days would be slower.

I have just timed the various solutions, and am surprised to find that DDAYS is quicker.
I am also disappointed that simply returning a value seems slightly slower than the evaluating an IF condition.

In seconds for 1 million iterations on Android I see

DDAYS 20
IF Integer 30
RETURN real 35

(I Need to repeat to see if timings are consistent )
