OfALargeWhole​(AngouriMath.​Entity,​AngouriMath.​Entity)

b ^ e mod m and n! mod m, for whole numbers b, e >= 0,
n >= 0 and m not 0, reduced modulo m as they are built, so the
power or factorial is never written out: 2 ^ (10 ^ 8) mod 1000 took 29 s and
13.9 GB, and 10 ^ (10 ^ 9) mod 7 did not finish in a minute. The remainder is
the floored one, as the operator's: |m| | n! once n >= |m|, so that is
0. Null otherwise, and for 0 ^ 0, which has no value.
