1,286 Pointshow to convert NSNumber to a float value?
Create a float variable called runningTotal. Then, create a for in loop which iterates through the array you created in step 1. When the loop finishes running, the value of 'average' should be the average of the values contained in temp. (NOTE: To convert an NSNumber, 'x', to a float, use [x floatValue] )
NSArray *temps = @[@75.5,@83.3,@96,@99.7];
float average;
float runningTotal;
for(NSNumber *num in temps){
float temp = [num floatValue];
runningTotal += num;
}
average = runningTotal/[temps count];
