Java code does better than ChatGPT?

I have recently worked on a project to calculate Asset depreciation methods using Java. I know computer programing but only a little about accounts. So, I asked ChatGPT to teach me. Here is what I have learned from ChatGPT. It is simply a clever and fantastic experience. Here is what I got from ChatGPT.

The Asset Depreciation Annuity Method is a way of calculating the depreciation expense of an asset over its useful life by treating it as a series of annuity payments. This method assumes that the asset will provide a fixed stream of benefits over its useful life, and that these benefits can be treated as a series of equal payments made at regular intervals

The formula for calculating depreciation expense using the Asset Depreciation Annuity Method is as follows:

Depreciation Expense = (Asset Cost - Salvage Value) * (Interest Rate Factor)


Where:

Asset Cost = the original cost of the asset
Salvage Value = the expected value of the asset at the end of its useful life
Interest Rate Factor = the present value of an annuity of $1 per period for the useful life of the asset at the given interest rate.
To calculate the Interest Rate Factor, we can use the annuity method equation:


Interest Rate Factor = (1 - (1 + r)^-n) / r

Where:
r = the interest rate per period
n = the useful life of the asset in periods
Once we have calculated the Interest Rate Factor, we can use it to calculate the depreciation expense for each period of the asset's useful life.


For example, let's say we have an asset that costs $10,000, has a salvage value of $1,000, and a useful life of 5 years. We will use a straight-line depreciation method and an interest rate of 5%. Using the Asset Depreciation Annuity Method, we can calculate the depreciation expense for each year as follows:
Step 1: Calculate the Interest Rate Factor

r = 5% / 1 = 0.05
n = 5 * 1 = 5
Interest Rate Factor = (1 - (1 + 0.05)^-5) / 0.05 = 4.3295


Step 2: Calculate the Depreciation Expense for Each Year

Year 1: Depreciation Expense = ($10,000 - $1,000) * (4.3295 / 5) = $7,463
Year 2: Depreciation Expense = ($10,000 - $1,000) * (4.3295 / 5) = $7,463
Year 3: Depreciation Expense = ($10,000 - $1,000) * (4.3295 / 5) = $7,463
Year 4: Depreciation Expense = ($10,000 - $1,000) * (4.3295 / 5) = $7,463
Year 5: Depreciation Expense = ($10,000 - $1,000) * (4.3295 / 5) = $7,463.        

Then, I wrote a simple Java program and a small test case using the ChatGPT example. Usually, programmers will self-evaluate whether the code is right. My bad; the Java result numbers aren't matched against the ChatGPT result. I doubted my code and refactored it, and all looks ok. Then I opened Google Spread tried the same calculation and found my code, and Google Spread was the same with a tiny precision difference.

ChatGTP = ($10,000 - $1,000) * (4.3295 / 5) = $7,463
Java Code = ($10,000 - $1,000) * (4.3295 / 5) = $7793.10
JavaScript = ($10,000 - $1,000) * (4.3295 / 5) = $7793.10        

OMG! Is ChatGTP incorrect? I can't believe this.

Then I asked a simple equation as follows,

ChatGPT = (10,000 - 1,000) * (4.3295 / 5) is 7,794.3.
Java Code = (10,000 - 1,000) * (4.3295 / 5) is 7793.100000000001.
JavaScript = (10,000 - 1,000) * (4.3295 / 5) is 7793.100000000001.        

ChatGPT is excellent in many aspects, but not in simple Maths!
