[Gambas-user] 2D-Array ?

[Caveat]

Don't shoot me for stating the obvious, but -ve means negative.

So I guess Bruce is just saying that intuitively he'd expect
round(float, int) to look like round(my_float, 2) if you wanted to round
my_float to 2 decimal places but in fact you need round(my_float, -2).

Kind regards,
Caveat
