Question: why can't Maple decide if 2+89^(1/2)>0 ?

Any idea why

if 2+89^(1/2)>0 then
   print("yes");
else
   print("no");
fi;

gives

Since 

evalf(2+89^(1/2))

is 11.4339.

I tried in Mathematica, and it works there

If[2 + 89^(1/2) > 0, Print["Yes"], Print["No"]]

What is the correct way to do this in Maple? i.e. to check that a numerical value is >0 ?

This is done in code, where the value I am doing this check on are known to be numeric, but I do not know what form they will be, I just know they will contain no floating point numbers. Only exact numbers.

The problem is the 89^(1/2). Maple knows it is >0 

is(89^(1/2)>0)

        true

but 

if (89)^(1/2)>0 then
   print("yes");
else
   print("no");
fi;

May be because 89 is prime. Should I replace my if with is for this check?
