Convert string to float in Objective-C

The proper way of doing this is

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

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

your_float = [your_string floatValue];

EDIT:

try this:

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