Is God a mathematician?
In computation, everything is finitely represented using bits, even real number approximations that are sometimes called floating point number (approximations).
English: "The beloved God has made all of the integers, everything else is the work of man." (Kronecker, Leopold, 1823-1891)
German: "Die ganzen Zahlen hat der liebe Gott gemacht, alles andere ist Menschenwerk" (Kronecker, Leopold, 1823-1891)
The important point here is not a Creator God. The important point is that real numbers appear to exist only in the mind of humans as a way to model problems and approximate solutions.
