< p class = "commentary firstcommentary" > < a id = "SP1_1" class = "paragraph-anchor" > < / a > < b > § 1.1. < / b > For a binary operation, note that "pi plus pi", "pi plus 3", and "3 plus pi"
must all use floating-point, whereas "3 plus 3" uses integer arithmetic: in
other words, if either operand is real, then real arithmetic must be used.
"Promotion" means converting an integer to a real number (I'm not quite sure
why that is traditionally thought of as being better) — in "pi plus 3", the
integer 3 is promoted to real.
