K&R C (pre-ANSI, pre-Std. C) specified that all floating point
expressions will be propagated to double. And parameter passing
is an expression. Thus, floating point values will always be put
on the stack as double, and printf expects them this way.

(If the formal parameter is a float, the function must read the 
double from the stack and store it back as a float before entering 
the body of the function.)
