I'm having a problem to convert an octal number literal for 16. Please help me!

It throws me an error like this: "mevol" does have the decimal value 16 but should be declared using an octal literal, i.e., a number starting with a zero followed by any number of digits using characters 0 to 7.

I did this: var mevol = 0x10; (But it doesn't work)

Hi Pablo,

Try this:

var mevol = 020;

You used a hexadecimal number, starting with 0x. The octal number starts with a 0 but doesn't use the x

That is the correct hexadecimal number. Reply back if you can't figure out the correct octal number.

I write var mevol = 14;

But it throws me an error like this: Bummer! Oops! You've set "mevol" to the decimal number 14 which is the octal literal 016. Try setting it to decimal number 16 by adding 2 to your octal literal 016.

How convert 016 to a decimal number 16 by adding 2? Thanks a lot!
