In math class, we were given an extra credit problem on our test, asking what positive integers will never fit the form of a^2+b^2=c^2 where a, b, and c are integral.

I wrote a program to solve it

my code was as follows:

```
Define xc()=
Prgm
Local a
While a<100 //I took a guess and said that if one leg is 2, the other will be less then 100
Disp a^2+2^2
Disp a
EndWhile
EndPrgm
```

I watched as the numbers scolled through, and attempted to see if there were 2 ints in a row. It worked, but I was hoping if anyone knew of a way to include an if statement with something that returned the number a was at, and the answer only when it was an int.

A continuation of this would be to do

```
Define xc()=
Prgm
Local a
local b
While b<100
While a<100
Disp sqrt(a^2+b^2)
Disp a
EndWhile
EndWhile
EndPrgm
```

while checking for ints.

Thank you
