Cut & Paste Decimal-to-Binary converter

Credit: Sidharta

Description: Looking back at when I was in college, there were many occasions when I had to convert decimal to binary numbers (especially on assignments). If only I had the following script! It's a decimal-binary converter that, well, converts decimal numbers to binary instead!

Example: Enter a regular number to see it get converted into binary form!

Directions: Simply cut and paste everything inside and paste it where you wish the converter to appear:

<SCRIPT language="JavaScript"> function check() { dec = document.DecToBin.deci.value; if (dec == "") {alert("please insert decimal number first."); } else {scan(dec);}; }; function scan(ok) { var chr="1234567890"; count=0; var ex; var h;var hasil=0; for(i=0;i<ok.length;i++) { ex=ok.charAt(i); for(f=0;f<10;f++) {h=chr.charAt(f); if(h==ex){hasil=hasil+1;}; }; }; if (hasil != ok.length) { alert("put number only ->'1234567890' ."); document.DecToBin.deci.value = ""; } else{bnr();}; }; function bnr() { var dec=new Number(); dec=document.DecToBin.deci.value; i=dec; var hit=""; while(i >= 1) { var m=(i*10)/4; while(m > 1){m=m-5;}; if(m < 0){i=(i-1)/2;hit+="1";}else{i=i/2;hit+="0";}; }; var b =""; var bin; bin=hit.length; for(a=hit.length;a>=0;a--) { b += hit.substring(a-1,a); }; document.DecToBin.deci.value=b; if (b.length > 15){alert("the answer is longer than the textbox -> "+b)}; }; </SCRIPT> <FORM name="DecToBin"><B>Insert Number:</B> <BR><INPUT type=text name="deci" size=15> <INPUT type="Button" value="convert!" onclick="check()"> </FORM> <p align="center"><font face="arial" size="-2">This free script provided by</font><br> <font face="arial, helvetica" size="-2"><a href="http://javascriptkit.com">JavaScript Kit</a></font></p>
