I need to get the number after de decimal point. For example I have:

344.567

And I need to get in a variable 567.

I've tried the next:

decimal d=43.3432332343344;

String s = String.valueOf(aa);

String[] arrayDecimal = s.split('.');

But the result is an empty array. How can I do this? Is there any way to get this?

In addition to the other answer, you can also use String.subStringAfter here as below (there could still be other ways to manipulate the string).

Decimal d = 43.3432332343344;
String s = String.valueOf(d); // assuming you meant to use d here
String afterDecimal = s.substringAfter('.');

You don't need to use String conversion at all to obtain the fractional part of a Decimal.

Decimal d = 5.6;

System.debug(d - d.round(System.RoundingMode.DOWN));

0.6

Decimal d = -5.6;

System.debug(d - d.round(System.RoundingMode.DOWN));

-0.6

Math.abs(d - d.intValue());

d = -7.81 returns 0.81

d - d.intValue();

d = -7.81 returns -0.81

But if you just want the string 81 - the fractional digits, then @sfdcfox answer is the way to go.
