# JavaScript, rounding number after decimal

etc

Given that, you have to work with many decimal number for example: 0.335, 0.345,
0.2, 96.6666. And then you want to round those number 2 digits after decimal.
The most general way is to used `toFix()`

. However, the behavior of `toFix()`

is
not good. Let test with value `0.335`

and `0.345`

.

The better solution is that, we try to use the first two digit after decimal, the only issue is that, these two digit up/down are depend on the third digit, perhaps the fifth one. Number 44 is to solve this issue. Any number `x.a-b-c-d`

which has `c-d`

>= 56, the `b`

will be round up by one.

A good solution come up with a compact function which can help you use in any time.
