    double dvalue = (double)value;

    NSArray *suffix = @[ @"", @"K", @"M", @"B", @"T", @"P", @"E" ];

    while ((value /= 1000) && ++index) dvalue /= 1000;

    NSString *svalue = [NSString stringWithFormat:@"%@%@",[NSNumber numberWithDouble:dvalue], [suffix objectAtIndex:index]];

    return svalue;
}
