Number converter is not converting digits after decimal point
Question
Actually I am a student and I had just started to programme in Javascript. I have created a binary to octal to hexadecimal to decimal converter which is working quite good but the digits after decimal point are not converted please help me as necessary
I can't figure out the problem
My project codes
<html>
<head>
<title> Convertor </title>
</head>
<body>
<input id="bin" oninput="Convert('bin', 2)" placeholder="bin" spellcheck="false">
<input id="oct" oninput="Convert('oct', 8)" placeholder="oct" spellcheck="false">
<input id="dec" oninput="Convert('dec', 10)" placeholder="dec" spellcheck="false">
<input id="hex" oninput="Convert('hex', 16)" placeholder="hex" spellcheck="false">
<script>
function id(id) {
return document.getElementById(id);
}
function Convert(s, n) {
if(parseInt(id(s).value, n)) {
if("bin" != s) { id("bin").value = parseInt(id(s).value, n).toString(2) }
if("oct" != s) { id("oct").value = parseInt(id(s).value, n).toString(8) }
if("dec" != s) { id("dec").value = parseInt(id(s).value, n).toString(10) }
if("hex" != s) { id("hex").value = parseInt(id(s).value, n).toString(16) }
} else {
if("bin" != s) { id("bin").value = "" }
if("oct" != s) { id("oct").value = "" }
if("dec" != s) { id("dec").value = "" }
if("hex" != s) { id("hex").value = "" }
}
}
</script>
</body>

Use parseFloat instead of parseInt to parse decimal numbers. You cannot pass the second argument - the radix - when using parseFloat .

Fathyb mentioned that parseFloat has no radix parameter. And there is a simple reason. What du you expect as result when converting 3.5 to binary? 3 equals 0000011 and 5 is 0000101. But 0000011.00000101 is not a valid binary format.
That means as far as i know your code is fine because floats are not supported. ;o)
