Question

I have a problem that I can not fix with a number, I’ll explain.
At one point in my code I call a function that returns an int, then I divide it and have a float with two decimal places.

My Ex 69033792 Fuzion back, I want to have to divide by 1024 and 67415.81
I write

NSInteger mem_0 = [self printMemoryInfo:@"0"];
    [self.mem1 setText:[NSString stringWithFormat:@"%.2f",(mem_0/1024f)]];

but I do not return the decimal part … What’s wrong?

thanks

myDouble = [[NSNumberFormatter alloc] init]; 
[myDouble setFormatterBehavior:NSNumberFormatterBehavior10_4]; 
[myDouble setNumberStyle:NSNumberFormatterDecimalStyle];
[myDouble setRoundingMode:NSNumberFormatterRoundHalfUp];
[myDouble setMinimumFractionDigits:0];
[myDouble setMaximumFractionDigits:2];
    NSInteger mem_0 = [self printMemoryInfo:@"0"];
    [self.mem1 setText:[myDouble stringFromNumber:[NSNumber numberWithDouble: mem_0/1024]]];
    [myDouble release];
