Hi folks,
I think I need some help understanding floats.
I have a class that calculates a balance and places it in a table
column. At the end of this method I NSLog the output like so;
NSLog(@"current balance is: %@",balance);
and get
current balance is: 18976.69
in the console. So far so good.
The method plonks the balance into a table and returns it to whence it
came. The table is sourced by the normal datasource delegate methods
and the column has a number formatter on it set to Decimal #,##0,00##
with half even rounding. I placed the last ##'s in there to check that
the floats weren't producing decimals with more than 2 places but in
my table column I get 18976.6995 which doesn't make sense. The float
calculation is exactly 2 decimal places, I know that for a fact and
NSLog proves it. Yet somehow, the table datasource appears to produce
random decimal digits where i have the last ##.
Am I totally misunderstanding something about floats? Or is the extra
##'s in the formatter making things up?
