如何将nsnumber转换为float

Question

I need to multiply the value of an nsnumber by a float but they are of course incompatible types. How can I cast the nsnumber to a float?

Answer 1

float result = [myNSNumber floatValue] * myFloat;

请检查NSNumber类参考中的“访问数值”部分，以转换为其他类型。

Answer 2

像这样：

float value = [someNSNumber floatValue];
