The punctuation in my third equation wasn’t correct. What I should have said was something like the following:
That equals this:
[(1.4 times 1.869973) times (10^20)] divided by (1.135288 times 10^21)
And, no, even a scientific calculator is not perfect for these sorts of problems. A scientific calculator is just one with various sorts of functions like logarithms, exponentials, factorials, permutations, and the various trigonometric functions. It is not the best way to work on very large and very small numbers. Scientific notation (where the numbers are split into coefficients and exponentials) can really be done much better on paper, using a calculator only for the places where you’re multiplying and dividing only the coefficients. Your scientific calculator may or may not be able to handle the numbers in the OP. For any given scientific calculator, there are numbers so large or so small that they mess up the calculations. Some computer packages are able to handle much larger and much smaller numbers.
Sorry, I still don’t get it.
Your link discusses astromonic distances. Which are measured in,well… astronomic numbers.
But that’s why god invented the AU (astronomic unit) and the light-year…so we can use big numbers more easily.
I still don’t understand what the OP is calculating, or what units he* is using.
(I’m assuming the OP is a he not a she. Because everybody knows girls hate math )
