I am trying to add two numbers in JavaScript, represented in hexadecimal base, in the following way:
var a = 0x0028 << 16 + 0x0010;
and what I expect to get is 0x00280010. Unfortunately JavaScript makes a equals 40, (which of course is 0x0028). If I shift the bits without adding 0x0010, everything works fine, I get 2621440 for a, which is 0x280000. Why adding 0x0010 yields such results for a. I am not that good at this kind of arithmetic, am I doing or expecting something wrong? Thank you all in advance :)
use brackets: + has higher precedence over <<.
var a = (0x0028 << 16) + 0x0010 // note the brackets.
