If it isn't and you intended p/0.01 to give you an integer value you can use as an index into n, you may encounter difficulties due to floating point arithmetic.0.1 is not exactly representable in finite binary floating point, just the same way that 1/7 is not exactly representable in finite decimal points, and when you increment a variable by 0.1 then even at the places that should logically be integers the result might be something that is not exactly an integer.Array indices must be positive integers or logical values.
