Javascript：在显示较大的unumber时如何避免科学计数法

Question

Based on http://users.dickinson.edu/~braught/courses/cs131s99/Lessons/03-Out&Data.html , for readability, JavaScript uses scientific notation to display very large numbers (absolute value greater than or equal to 1021). For example, the write statement

document.write(1000000000000000000000000);

would produce the output 1e24

Can I avoid scientific notation display?

Thanks

Answer 1

It's not for readability. If an integer is larger than 2 ⁵³ (9007199254740992), then JavaScript cannot guarantee its exact storage. In your case the number is actually 999999999999999983222784.

You can use something like YourJS.fullNumber() . For instance you could try something like YourJS.fullNumber(1e20) to produce 100000000000000000000 . Try out your own code here:
