NSNumber declaration

I was doing the code challenge and put the following answer. NSNumber *planck = [NSNumber numberWithFloat:6.626]; This works in xCode but it won't accept this answer.

What did I do wrong?

NSNumber *planck = @6.626;

for negative values you can use NSNumber * number = @(-4.220);
