Reading your comment to Marek's answer it looks like your string actually = @"$3.45"

To convert that to a float use:

NSNumberFormatter * formatter = [[[NSNumberFormatter alloc] init] autorelease];
formatter.numberStyle = NSNumberFormatterCurrencyStyle;
formatter.currencyCode = @"USD";

float value = [[formatter numberFromString: @"$3.45"] floatValue];
