I have NSNumber objects stored in an NSMutableArray. I am attempting to perform a calculation on each object in the array.

What I want to do is:

1) Take a random higher number variable and keep subtracting a smaller number variable in increments until the value of the variable is equal to the value in the array.

For example:

NSMutableArray object is equal to 2.50.

I have an outside variable of 25 that is not in the array.

I want to subtract 0.25 multiple times from the variable until I reach less than or equal to 2.50. I also need a parameter so if the number does not divide evenly and goes below the array value, it resorts to the original array value of 2.50.

Lastly, for each iteration, I want to print the values as they are counting down as a string.

I was going to provide code, but I don't want to make this more confusing than it has to be.

So my output would be:

VALUE IS: 24.75
VALUE IS: 24.50
VALUE IS: 24.25

…

VALUE IS: 2.50
