DoyleChris98 Posted January 31, 2015 Share Posted January 31, 2015 I have a Number from a prompt stored as FREQ, now i want to convert it to HEX, For entry into another variable. 1200 (B10) = 4B0 (B16) but if i put 1200 in as HEX (B16) that turns out 4608 in a converter on my phone. I need to get to 4608. not sure how to take 1200 and turn it into 4608. Link to comment Share on other sites More sharing options...
davej Posted January 31, 2015 Share Posted January 31, 2015 So you expect it to "magically" know whether you have entered decimal or hex? That is impossible. <!DOCTYPE html><html lang="en"><head><meta charset="utf-8"/><title>title</title><style></style><script>window.onerror = function(a, b, c, d){alert('Javascript Error:n'+a+'nURL: '+b+'nLine: '+c+' Column: '+d);return true;}</script><script>'use strict';window.onload = init;function init() {document.getElementById('btn1').onclick = put;}function put(){var x = document.getElementById('in1').value;document.getElementById('outp').innerHTML = 'dec-to-hex = ' + Number(x).toString(16) +'<br/>hex-to-decimal = '+ parseInt(x, 16);}</script></head><body><input type="button" id="btn1" value="Enter"><input type="text" id="in1" value="1200"/><div id="outp"></div></body> </html> Link to comment Share on other sites More sharing options...
