Assignment on Javascript

[nchgoguy]

This is homework due soon, and I am lost. Due in a few hours. I'm stuck, and looking for how to do this. Any suggestions?

This time the numbers that you are converting range from zero to one-hundred thousand.

As with Project 7, you are to write an HTML page, complete with a header, title and a body containing a JavaScript script. The general page describes the behavior of the script. The script first prompts the user for an integer number between 0 and 100,000. Next, the script checks that the user entered a number within the specified range and generated the English name for that number. For instance, if the user entered the number "67,231", the script would generate the name "sixty-seven thousand two hundred and thirty-one". The generated name is inserted in the page, toward the bottom, with an appropriate explanation.

Here is one for Roman numerals. Just rearrange it a bit for your homework.
:
[CODE=javascript]function check_romandec( ){
String.prototyp e.fromRoman= function(){
var num= '', sum= 0, tem;
var rGA= [['DCCCC','CM'],['LXXXX','XC'],['VIIII','IX'],['CCCC','CD'],['XXXX','XL'],['IIII','IV']];
if(/\D/.test(this)==fa lse){
num= Number(this).to Roman();
for(var i= 0; i<6; i++) num= num.replace(rGA[i][0],rGA[i][1]);
return num;
}
else{
var rX= / [^IVXLCDM]/;
num= this.toUpperCas e();
if(rX.test(num) ) return '';
for(var i= 0;i<6;i++)num= num.replace(rGA[i][1],rGA[i][0]);
var rN= {I:1, V:5, X:10, L:50,C:100, D:500, M:1000};
var rNA= num.split('');
var nA= new Array;
for(var i= 0; i<rNA.length; i++){
var tem= rNA[i];
nA[i]= rN[tem];
}
i= 0;
while(i< nA.length-1){
if(nA[i]< nA[i+1]) return '';
else sum+= nA[i];
i++;
}
num= sum+nA[i];
}
return num;
}
Number.prototyp e.toRoman= function(){
var num= '',tem;
var n= Math.floor(this );
var aN= [1, 5, 10, 50,100, 500, 1000];
var rN= ['I','V','X','L' ,'C','D','M'];
for(var i= 6; i>= 0;i--){
if(n> aN[i]){
tem= Math.floor(n/aN[i]);
while(tem>0){
num+= rN[i];
tem--;
}
n= n%aN[i];
}
}
return num;
}
return true;
}[/CODE]

Math.floor(n/aN[i]) is sure to impress your instructor.

nchgoguy,

The experts on this site are more than happy to help you with your problems but they cannot do your assignment/program for you. Attempt the assignment/program yourself first and post questions regarding any difficulties you have or about a particular function of the code that you don't know how to achieve.

Please read the Posting Guidelines and particularly the Coursework Posting Guidelines.

Then when you are ready post a new question in this thread.

Not if he can't explain what it does! :)

Ooh, that's nasty(!) - a nice pun though!

I personaly believe that's ok as long as you explain the code making it a learning experience.

What does it do exactly?

What does it do exactly?

It divides the number by the current decimal and returns an integer (by 'flooring' the result). For example, if the number was 5050, Math.floor(n/aN[i]) would give Math.floor(5050/1000) which equals 5. This allows the while loop to get 5 Ms.
