Hi, I want to be able to say the following with mathematical symbols; 1) A is any integer. 2) A is a non-integer (not a whole number). Please help. Thanks
[itex]A[/itex] is an integer: [itex]A\in\mathbb Z[/itex]. [itex]A[/itex] is not an integer: [itex]A\notin\mathbb Z[/itex]. [itex]A[/itex] is a real number which is not an integer: [itex]A\in\mathbb R\backslash\mathbb Z[/itex]. [itex]A[/itex] is not a whole number: [itex]A\notin\mathbb Z_+[/itex].
