Currently, I am facing a challenge with my program that involves converting integers to binary and decimal. While the binary conversion is working fine, I am encountering difficulties with the decimal part. I am considering using the function intToFloat, but I am uncertain if it is the correct approach. Below is the code for the conversion functions:
if (cT[0].checked) {
// to binary
var dval = parseInt(val);
if (isNaN(dval)) {
alert("input value is not a number");
}
else if ((val % 1) !== 0 ) {
alert("number is not an integer");
}
else if (dval < 0) {
alert("Input value must be a positive integer");
}
else {
convertByArray(dval);
}
}
else if (cT[1].checked) {
//to decimal
var dval = parseFloat(val);
if (isNaN(dval)) {
alert("input value is not a number");
}
else if ((val % 1) !== 0 ) {
alert("number is not an integer");
}
else if (dval < 0) {
alert("Input value must be a positive integer");
}
else {
intToFloat(dval);
}
}
else {
alert("Please select a conversion type.");
}
}
function convertByArray(dval) {
var rA = new Array();
var r,i,j;
i=0;
while (dval > 0) {
r = dval % 2;
rA[i] = r;
var nV = (dval - r) / 2;
$("txtCalc").value = $("txtCalc").value + " Decimal " + dval + " divided by 2 = "
+ nV + " w/Remainder of: " + r + "\n";
i += 1;
dval = nV;
}
for(j=rA.length-1; j>= 0; j--) {
$("txtOut").value = $("txtOut").value + rA[j];
}
}
function intToFloat(num, decPlaces) {
return num + '.' + Array(decPlaces + 1).join('0');
}
This program should display the output of an integer being converted to a decimal, providing the value as well, similar to how it currently displays the conversion to binary.
