Absolute nonsense. 123.456 is a numeric value, but it is not an integer.

That is, in fact, the definition of an integer: a number that has no
fractional part. There is no "argument" about it, except by the uninformed.

C, the set of counting numbers, is {1, 2, 3, ...}
W, the set of whole numbers, is C and zero: {0, 1, 2, 3, ...}
I, the set of integers, is W and the negatives of C: { ..., -3, -2, -1,
0, 1, 2, 3, ...}
