Question

How to create number 1e6 with javascript?

var veryLargeNumber = //1e6 

Answer 1

Here are some ways:

 var veryLargeNumber = 1e6; var veryLargeNumber = 1.0e+06; var veryLargeNumber = 1000000; var veryLargeNumber = 0xf4240; var veryLargeNumber = 03641100; var veryLargeNumber = Math.pow(10, 6); 

Answer 2

It is written as you wrote it: var notVeryLargeNumber = 1e6 .

Answer 3

As you wrote above:

 var veryLargeNumber = 1e6;//Equals to 1*10^6 

Answer 4

This works great for me.

 var veryLargeNumber = 1e6; console.log( veryLargeNumber ); 

outputs:

1,000,000

Answer 5

For the curious, I went to study a little safari ...

Although E denotes an exponent, the designation is usually called the (scientific) designation E or the (scientific) designation

...

Since indexes with an index such as 10 ^ 7 may not always be conveniently displayed, the letter E or e is often used to represent "ten times magnified to a power" (which will be written as "× 10n"), followed by exponent value; in other words, for any two real numbers m and n, using "mEn" will indicate the value m × 10n.

Use exponential notation if the number starts with "0." and then more than five zeros. Example:

 > 0.0000003 3e-7
