<script language="javascript">

for (x = 0; x < 127; x++) {

document.write("Decimal: ", x.toString(10), " Binary: ",
x.toString(2), "<BR>")
}
</script>


Result is:
Decimal: 0 Binary: 0
Decimal: 1 Binary: 1
Decimal: 2 Binary: 10
Decimal: 3 Binary: 11
Decimal: 4 Binary: 100

How could make the result with 5 signs for example as:

Decimal: 0 Binary: 00000
Decimal: 1 Binary: 00001

and so on

Code:

document.write("Decimal: "+x.toString(10)+" Binary: "+"00000".substring(0,5-x.toString(2).length)+x.toString(2)+"<BR>")

This will only show 5 numbers if x<32. If x>=32 there will be 6 or more binary digits.
