Very stupid question but on the internet I have found different results and I would like to be sure.
how much is worth 5e+20?
Or better how much is “e” and how does it work?
I was looking at this documentation precisely: https://docs.coronalabs.com/api/type/Number.html
that “e” doesn’t itself have a value, rather it’s an abbreviated exponent: “5e20” == “5 x 10^20” (five hundred quintillion)
(there IS another very important, and related, “e” in math that does have a specific value, but that’s not the context here)
Perfect thank you so much I wanted to know how it was used in the corona context
It’s not a Corona context. It’s a math context. “e” in math is still valid in Corona. See math.exp(), more specifically e = math.exp(1)
http://docs.coronalabs.com/api/library/math/exp.html
In your first reference that Dave explained, number e exponent is number * 10 to the exponent power (val = 5 * 10^20) but the other use of “e” is the math constant e = 2.718281828459
