The type of a constant expression is determined by the type of its elements. If it contains only numeric literals, its type is ideal -integer or ideal float (§Ideal number). Whether it is an -integer or float depends on whether the value can be represented -precisely as an integer (123 vs. 1.23). -(TODO: Not precisely true; 1. is an ideal float.) +integer or ideal float (§Ideal number). Whether a literal +is an integer or float depends on the syntax of the literals (123 vs. 123.0). The nature of the arithmetic operations within the expression depends, elementwise, on the values; for example, 3/2 is an integer division yielding 1, while 3./2. is
