Try 20 * BILLION; it will overflow if not careful.

 
(Actually both 10/20 billion will overflow u32; I was thinking of 20
billion billion overflowing u64.)
 

I'd normally write '20 billion' outside of C, since I use such
numbers, with lots of zeros, constantly when writing test code.

Is not it "20 milliards" in British English?

 
We (UK) now use 'billion' for 1E9; in the past it meant 1E12.
 
'Milliardo' is Italian for 'billion'; perhaps in a few other languages too.

It's "miliardo", like "milione" (1e6), but there is also "bilione"(1e12), All
with only one "l".
