roundup the numbers before comparing

I think for Test-7 , problem creator @Tanya should add "~" to the "flag_correct" part of the line:

assert(isequal(isTherePythagoreanTriple(a, b, c, d),flag_correct))

so it should be changed to :
assert(isequal(isTherePythagoreanTriple(a, b, c, d),~flag_correct))

Pythagorean triplets are taken as positive integers , one of the test case uses irrational number for inputs ! I wish the test creator
@Tanya Morton makes appropriate change as suggested by @Sophia
