Graphing Calculator Problem?

Occasionally, when I put in a calculation in my graphing calculator, it comes up with a number that doesn’t seem to be correct -ending with an “E-5 or E64”. What does this mean? My calculator is a Ti-84 PlusExamples: 2.71838 to the -7.5 power = 5.529345821 E-4The permutation of 50 = 3.04140932 E64Thank you so much for your help!!!

E-4 means 10^(-4), or 10 raised to the power of -4.E64 means 10^(64), or 10 raised to the power of 64.Edit: In other words, the number is either too large or too small to be displayed.Example: 6 million = One “6” and six “0”s.or 6 million = 6E6... Show More
