for(x=0; x<=255; x++)
{
document.writeln("toHex(" + x + "): " + toHex(x) + "<br>");
if(x%16 == 15)
document.writeln("<p>");
}
Conclusive testing for this function is easy: this code simply sets up a for loop that loops through the
values 0 to 255, calling the toHex function for each value. Once again, the test value is printed to the
screen as well as the result to ensure that the function is working correctly.
Although it was not necessary to the testing procedure, I added some extra code to put a new
paragraph marker in after every 16th loop. This will help format the output into blocks of 16, and make
it easier to understand hexadecimal numbering.
