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];

NSString's: - (float)floatValue;

For example:

NSString *str = @"3.45";
float f = [str floatValue];
