(0).to(2) vs 0.to(2)

Posted: Dec 27, 2014 9:05 AM

Hi,

Started a new year's (2015) resolution (digging into Scala) a bit early :-)

What is the difference between (0) & 0 in the followings:
for (i <- 0.to(2))
...
and
for (i <- (0).to(2))
...

Is (0) a Tuple1?

Thanks,
Q

Isn't that "(0)" just a parenthesized expression whose inner expression is "0" (of type Int)?
