This model seems to be the functionally equivalent European version of the TI-36X Pro. I'm happy to report that all the bugs mentioned in this blog post and on the Wikipedia page for TI-36X Pro seem to be fixed in this version. (My calculator refuses to make a mixed fraction out of (625 pi) / 4. Even the small formatting bugs like °K instead of K have been fixed.)<br /><br />The TI-30X Pro MathPrint is *not* physically equivalent to the TI-36X Pro, though. Besides the different case design it also has 2 CR2032 batteries instead of one. Internally the model number is SR36 while the TI-36X is internally a SR21, I think.Edwin Steinerhttps://www.blogger.com/profile/15616273828572365838noreply@blogger.comtag:blogger.com,1999:blog-1597214980833186328.post-73832479691046181332019-11-19T22:53:33.462-08:002019-11-19T22:53:33.462-08:00CompTIA Security plus certification training Check...<a href="https://www.crack4sure.com/CompTIA-Security-plus-certification-training.html" rel="nofollow">CompTIA Security plus certification training</a> Check out free demo of all certifications Exam.

Your answer will be x=-5, which is correct. Now here is the error, "when a previous num-solver gives you a negative value, like this one, it messes up your next num-solver."<br /><br />Now that you have x=-5. Repeat the process using a different equation, such as x^2=12^2+20^2. This equation is also known as the pythagorean theorem. Your answer will come out -20, even though the answer should be 20. This happens with all types of equations. That was just an example. <br /><br />Now, you're probably thinking, why not just change the "X value to 0" when solving for an equation, this will eliminate the negative value. <br /><br />WELL.....Because that also gives errors. <br /><br />For example. Try this equation 4.905x^2 = 17.68x when x=0 or even x=1. When you solve this equation, and many more!!! you get your new answer to be x=0. Which is wrong. However, if you change x to some other number like 2, you get x=3.6. Which is correct!!. This error happens when x=0 and x=1 and x=666666. And I"m sure it does it with more previous x values, I just haven't noticed it so far or even wasted my time trying to test it.<br /><br />If anyone has a solution, please post it, because I find myself avoiding the num-solver all together. <br /><br />CSUF student.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1597214980833186328.post-45744216614148339192014-09-23T11:57:18.981-07:002014-09-23T11:57:18.981-07:00Update on the TI36x Pro Bug
I am posting today to...Update on the TI36x Pro Bug<br /><br />I am posting today to give everyone an update on the status of this problem. TI attempted a fix of this problem (sometime around Jan 2014) but the problem persists, but is nuanced a bit from the video, hence my post update.<br /><br />My calculator has a manufacturing code of K-0614B which means it was assembled in June of 2014, and yes, my machine has this bug also, and YES it is a bug.<br /><br />What 'triggers' the bug in the later level models of the TI36x Pro is the mixed number conversion algorithm [math] [1] [enter]. Once that happens EVEN once, the calculator will show incorrect results with PI in MathPrint. Again, clearing the memory (reseting the machine) clears the bug temporarily until the next mixed number conversion. <br /><br />One, avoid mixed number conversions combined with PI. Two, be careful to clear the calculator after mixed number conversions if PI calcs are going to be subsequently performed. Three, you might want to set your MODE to engineering, and Classic. Remember, clearing the memory also sets your MODE to defaults!<br /><br />OK, so let's see how this is nuanced on a 2014 TI36x Pro:<br />Clear the memory by holding [on] and pressing [clear], then press [clear].<br />Type [math] [1] [enter] (this will trigger the bug)<br /> 0 returns 0<br />Type PI 12.5 ^2 [<>] [enter]<br /> 156 PI/4 ouch, there is our bad result<br />(but now watch this, TI got half the fix right)<br />Type [<>] (to toggle back to decimal)<br /> SYNTAX Error (whoa--- TI knows the form is bad!)<br /><br />For those of you who might still be confused by this, by definition a mixed number may not contain a transcendental number in any of its parts; by definition the parts must all be whole integers. So, having PI as a numerator component of the fractional part of the mixed number is bogus; and this is still happening on recent deliverables from TI ONCE the mixed number conversion algorithm has been tripped.<br /><br />I spoke with a rep from TI this morning and was told 'he' has never heard of it... he even asked me to walk him through the scenario, which I politely did. He told me he would report it ! ~nice, huh?<br /><br />So, you have several options:<br />1) set the mode of your calculator in Classic, and Eng (three decimals) and leave it there; but, be aware that clearing the memory resets the defaults!<br />2) Avoid mixed number conversions with PI<br />3) Avoid mixed number conversions completely, and be careful to reset the machine if subsequent PI calcs are necessary.<br /><br />The rep at TI said they DO NOT EVER recall calculators with bad logic. They DO replace or refund within the warranty period. He told me they would prefer I return it to the store if purchased within the first 30 days of the warranty period. <br /><br />So, don't hold your breath for a fix, and never expect a recall--- having said all this, I'm not returning my calculator. It will probably be worth a lot of cash someday to calculator collectors (like me) because of this flaw--- depending on how many survive for the next thirty years! Beyond that, for the price, its still a fairly robust little machine!<br /><br />Cheers folks!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1597214980833186328.post-91247426848807613662014-06-19T10:51:01.057-07:002014-06-19T10:51:01.057-07:00No. The bug is still there.
