Because the - toFixed - method returns a string.

when you want to use the variable as a number use eval() to return a
number

No thanks, I will use the unary plus operator, the Number constructor
called as a function, parseInt or parseFloat, depending on the
situation. The - eval - function would be the absolute worst method to
use, particularly as its behaviour is unpredictable whenever its
argument is a string that does not represent a number.

You probably know more about Javascript, but I have been coding for
about 2 years and the - eval - function has always worked for me.

You suggested using - eval - so we are well past "probably".

but I have been coding for about 2 years

It might be an idea to stop and RTFM soonish.

and the - eval -
function has always worked for me.

Even the worst ways of doing things 'work', otherwise they become the
best ways of not doing them.

There are such things as manners--this sentence was probably
unnecessary.

You mean you know a script engine where eval("2") doesn't return
typeof "number"? Which one is that (non-ECMAScript compliant by
default)?

If you foresee some dangerous consequences of eval("2") in comparison
of the +"2" trick then you should spell them for the public attention
IMHO. After all eval is not a sex with underagers or drugs to get
berserk on the combination of these four letters by itself, IMHO.

Who said I did? I didn't. Anybody that uses eval(string) to convert
string to a number is an incompetent ignorant idiot.

ECMAScript, concern, mouses rear end.

Somewhere on this planet, your village misses you very much.

And anyone who uses instead +"2" trick instead is a highly intelligent
experienced master who's even sh** smells just like roses? :-)

Cool... Got it... Some men are so easy to please, really :-)
