Error in the Exponent 

A number that is given with very large uncertainties, such that it might be ten or a hundred (or more) times larger or smaller than the value given. Astrophysics is famous for having 'errors in the exponent'

..."We estimate the minimum viable population to be somewhere between 100 and 5000" (extremes from the wikipedia article)

... "in our universe protons decay with a time scale in the range 10^33 - 10^45 years"

These quantities don't have an error in the value, they have an error in the exponent.

{"error":"An error occurred."}

It is an error that happens when you just search random symbols in the Urban Dictionary. I typed "":" and "~_+{}|:"<>?" but it made the same error.

Person 1: Hey Person 2! I was just typing random symbols in the Urban Dictionary but I keep getting this same error: {"error":"An error occurred."} .

Person 2: Oh yeah that just happens when you type symbols and some symbols that the Urban Dictionary can't handle even though these: ~, _, +, {, }, |, :, ", <, >, ?, `, -, =, , , \, ;, ', ., /, and , typed singular it still works.
