# Dec2Hex

Converts a decimal value into a hex value. This helps converting RGB colors to HEX.

```function dec2hex(n){
n = parseInt(n); var c = 'ABCDEF';
var b = n / 16; var r = n % 16; b = b-(r/16);
b = ((b>=0) && (b<=9)) ? b : c.charAt(b-10);
return ((r>=0) && (r<=9)) ? b+''+r : b+''+c.charAt(r-10);
}

/*
Examples:
---------

rgb(255, 0, 0) = red color = FF0000

dec2hex(255) => FF
dec2hex(0) => 00
dec2hex(0) => 00

------------------------------------

rgb(215, 230, 250) = light blue = D7E6FA

dec2hex(255) => D7
dec2hex(0) => E6
dec2hex(0) => FA
*/```

one small comment ;)

rgb(215, 230, 250) = light blue = D7E6FA

dec2hex(255) => D7
dec2hex(0) => E6
dec2hex(0) => FA

should be:

rgb(215, 230, 250) = light blue = D7E6FA

dec2hex(215) => D7
dec2hex(230) => E6
dec2hex(250) => FA

;)
There is a built-in javascript method for this:

n.toString(16);
(215).toString(16); // "d7"
