Answer 2

If you don't provide your code, we're not able to help you fixing it ^^

Answer 3

It seems to have Php code inside, so you need to run it on a server handling Php (even at least a local server)... On code playground you need to copy paste it to a 'php' project rather than in the html tab of a 'web' project: do that, and tell us if you've the expected output or not (actually does'nt output NaN if rub in php code playground project ;))

[edit]
your second link seems wrong ^^

Answer 7

I don't quite understand what you are asking, but in JavaScript you can use "var num = Number(string)" to convert a string to a number value.

Answer 8

but i don't input any string james, i just input a number, but output show "NaN", its my problem in coloumn Probalitu waiting client

Answer 9

I just noticed. There is no ^ operator in javascript. You need to use Math.pow().

Answer 10

i will try tomorrow james, thanks for suggestion bro

Answer 11

And I think Math.E will get the e constant, instead of approximating it as a regular number.

Answer 12
