如何防止极小的数字转换为科学计数法？

Question

I have to use very small numbers:

var x = 0.00000006;

When I run console.log(x) , it shows:

6e-8

I don't want it to show 6e-8 , I want it to show 0.00000006 .

Later I need to plot it on a graph, so I can't convert it to a string. How to keep it a small number without converting it to a string or scientific notation?

Answer 1

You can leave your number as it is. The 6e-8 is just the way your console represents this small number. To print it "pretty", just write a function to convert it into 0.00000006 , eg console.log(prettyfy(x)) . This way, you leave your number as it is and can print any number in your desired format.

Answer 2

You can convert it to "fixed" shape and get it to look like you want. Example would be:

var number = 6e-8; //this is your number
number = number.toFixed(8) //but since you won't always know how many decimal points you have you can use something like
number = number.toFixed(number.toString().split('-')[1]); //where you split your number, see how many decimals it has and pass that number to .toFixed method
