The following code example of NSLog function prints the value of float variable. You can use the technique discussed here in  your iPhone application to test and debug the code.

Here is the code example of NSLog function that prints the value of float.

//
//  PrintFloat.h
//  DataTypes
//
//

#import <Foundation/Foundation.h>

@interface PrintFloat : NSObject

{

    float _float;

}

-(void) print;

-(void) set_float: (float) n;

@end

The class implementation code is as follows:

//
//  PrintFloat.m
//  DataTypes
// 

#import "PrintFloat.h"

@implementation PrintFloat

-(void) set_float: (float) n

{

    _float = n;

}

-(void) print {
    NSLog(@"float value is: %f", _float);
}

@end

The %f is used here in the above example.
