如何有效地将NSInteger转换为NSDecimalNumber

Question

So I want to do NSInteger -> NSDecimalNumber for decimal computation purpose. 所以我想做NSInteger -> NSDecimalNumber用于十进制计算。

However, the way I am currently doing it, is using NSNumber as an intermediate. 但是，我目前的方式是使用NSNumber作为中间件。

NSInteger -> NSNumber -> NSDecimalNumber

NSInteger myInteger = 41234312;
NSDecimalNumber *myDecimal = [[NSNumber numberWithInteger:myInteger] decimalValue];

Is there a more efficient way to perform this conversion? 有没有更有效的方法来执行此转换？

Answer 1

You don't need to convert it to NSNumber , You can use : 您不需要将其转换为NSNumber ，您可以使用：

NSDecimalNumber *myDecimal = [NSDecimalNumber numberWithInteger:myInteger];

NSDecimal number is a subclass of NSNumber so you can directly use this method. NSDecimal数是NSNumber的子类，因此您可以直接使用此方法。
