#PB_Round_Nearest as default parameter for Round()

[AND51]

Well, if you read the title, what should I add?
Yet, there is no default parameter, so IMHO it's better to have one than to have none.

1Up

And besides of that, the manual says:

Description

Round the specified float number according to the given mode. If Mode = 0, it round down the number (keep only the integer part). If Mode = 1, it round up the Number

please replace 0 and 1 by the constants name...
