Another mathematician might like to comment here.  :)

e can mean 2 different things, was this a calculator display?

 

If it was then I expect it means

 

1.8915071e+19     =    \(1.8915071\times 10^{19}\)

 

e is also the symbol used for euler number or napier's constant.  

This is confusing too because most people call it the Euler number but Euler's constant is a different number again. sad

 

anyway

e = 2.7182818284590452

 

so it could mean

\(1.8915071\times e^{+19}\)

 

1.8915071*e^+19 = 337600539.4962055425176993

 

Or maybe I was not meant to insert the power sign and it could mean

 

1.8915071*e   +19 = 24.1416493783312661

1.8915071e+19. This number is a "computer-speak" for scientific notation. "e" in this context stands for "exponent" and "+" means that the exponent is "positive". The number can be written in a more familiar way thus:1.8915071e+19 =1.8915071 x 10^19 =18,915,071,000,000,000,000
