how can I convert a nsnumber into a float

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

float result = [myNSNumber floatValue] * myFloat;

Please check the "Accessing Numeric Values" section from NSNumber class reference for converting to other types.

Like so:

float value = [someNSNumber floatValue];
