Convert string to float in Objective-C

Question

How do I convert a string to a float in Objective-C?

I am trying to multiply a couple of strings I am getting back from JSON:

float subTotal = [[[[pu         


        

Answer 1

your_float = [your_string floatValue];

EDIT:

try this:

  NSLog(@"float value is: %f", your_float);

Answer 2

The proper way of doing this is

NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
numberFormatter.numberStyle = NSNumberFormatterDecimalStyle;

float value = [numberFormatter numberFromString:@"32.12"].floatValue;
