Discussion Overview

The discussion revolves around the calculation of .001 raised to the 100th power on TI-83 calculators, focusing on the accuracy and limitations of such calculations in different calculator models. Participants explore the implications of calculator memory and precision in handling very small numbers.

Discussion Character

  • Technical explanation, Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions why their TI-83 calculator returns zero for the calculation, suggesting it may be due to the answer being negligible.
  • Another participant agrees, stating that calculators cannot store numbers with infinite digits and are prone to rounding errors with very small numbers.
  • A participant provides a mathematical breakdown of the calculation, expressing that .001 to the 100th power equals 10^(-300), which is a very small number but not zero.
  • One participant mentions that their TI-84+ cannot handle exponents greater than 99 or less than -99, implying a memory limitation that may affect the TI-83 similarly.
  • Another participant notes that even in scientific or engineering mode, the TI-83 displays "0E0," while other models like the TI-85 and TI-89 provide a more precise output of "1.00E-300."
  • A later reply acknowledges the simplicity of the calculation and expresses gratitude for the insights shared regarding the TI calculator issues.

Areas of Agreement / Disagreement

Participants generally agree on the limitations of the TI-83 and similar calculators in handling very small numbers, but there are differing views on the implications of these limitations and the accuracy of the outputs.

Contextual Notes

Participants highlight potential limitations related to calculator memory and precision, as well as the dependence on calculator models for handling extreme values in calculations.

This is probably an ignorant question...but why when I attempt to calculate .001 to the 100th power on my TI-83 does it give me an answer of zero? Is the calculator assuming that the answer is so close to zero that it is negligible? If so, that's probably not the accuracy I'm looking for.

Yup, the calculator sees it just like a 0. Calculators can't store numbers with inifinite digits, plus you get roundinig erros with very small numbers.
 
.001 = 10^(-3)

.001^(100) = (10^(-3))^100 = 10^(-300) = 0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001
 
My TI-84+ can't handle anything with exponents greater than 99 or less than -99, probably some sort of memory limitation. I don't think the 83 is any better. You can probably find better arbitrary precision calculators online, or the TI-89 seems to handle this calculation fine. (Although, for something like this, you would just figure it out normally like Diffy did.)

That's interesting. Even in "scientific" or "engineering" mode, the TI83 gives an answer of "0E0".

The TI85 and TI89, however, give "1.00E-300".
 
Ok...that makes sense. And yea I suppose it's pretty simple to work out mentally; I just wanted to diagnose my TI's issues. Thanks for the insight:)
