How to do a rem while loop?

Hello everyone. I need the h value to be an integer, I can't have decimals. Therefore, I think a while loop with the function rem is needed but I have no idea how to do it.

while true
    h = input('Enter the desired grid spacing: ');
    if isnumeric(h) && isscalar(h) && h > 0 && rem(h,1) == 0; break; end
end
