去除浮点型小数点后的0

从后台获取或的浮点型数据，有的入12.000000或12.050000显示的很别扭。需要把后面的0去调。代码如下：

- (NSString *)translateXiaoShuDianWithFloat:(CGFloat)num
{
    NSString *finish = nil;
    NSString *floStr = [NSString stringWithFormat:@"%f",num];
    NSArray *numArray = [floStr componentsSeparatedByString:@"."];
    if([[numArray objectAtIndex:1] integerValue] == 0)
    {
        finish = numArray[0];
    }
    else
    {
        finish = [self bianliFromStr:floStr];
    }
    return finish;
    
}

- (NSString *)bianliFromStr:(NSString *)str
{
    if(![str hasSuffix:@"0"])
    {
        return str;
    }
    
    NSInteger strLength = str.length;
    NSString *string2 = [str substringWithRange:NSMakeRange(0, strLength-1)];
    return   [self bianliFromStr:string2];
    
    
}

如此就可以了。
