以下是格式化int,float,double和long型的示例
//
// PrintFormat.h
// DataTypes
//
//
#import <Foundation/Foundation.h>
@interface PrintFormat : NSObject
{
}
-(void) print;
@end
实现部份
//
// PrintFormat.m
// DataTypes
//
//
#import "PrintFormat.h"
@implementation PrintFormat
int num=90;
float _num=90;
double number=700.000;
long mlong=30;
-(void) print{
NSLog(@"The value of integer num is %i", num); //for integer the format specifier is %i
NSLog(@"The value of Long number is %i", mlong); //for Long the format specifier is also %i
NSLog(@"The value of float num is %.2f", _num); //for float the format specifier is %f and we can restrict it to print only two decimal place value by %.2f
NSLog(@"The value of double num is %f", number); //for Double the format specifier is %f (double can be represented in %e ,%E (in this it will be in exponentail form as well as in %e) , %g ,%G )
}
@end
