Converting Number to Words Javascript Indian Format

The Below code is used for number to words conversion ( Indian Format). The logic used can be implement in any other language. I have used java script here but if you understand the logic then you can recreate it using any other language.



Enter the Number here.




The Code for the above logic is as follows.


<script language="javascript">


function numToString(x)
{
var r=0;
var txter=x;
var sizer=txter.length;
var numStr="";
if(isNaN(txter))
{
alert(" Invalid number");
exit();
}
var n=parseInt(x);
var places=0;
var str="";
var entry=0;
while(n>=1)
{
r=parseInt(n%10);

if(places<3 && entry==0)
{
numStr=txter.substring(txter.length-0,txter.length-3) // Checks for 1 to 999.
str=onlyDigit(numStr); //Calls function for last 3 digits of the value.
entry=1;
}

if(places==3)
{
numStr=txter.substring(txter.length-5,txter.length-3)
if(numStr!="")
{
str=onlyDigit(numStr)+ " Thousand "+str;
}
}

if(places==5)
{
numStr=txter.substring(txter.length-7,txter.length-5) //Substring for 5 place to 7 place of the string
if(numStr!="")
{
str=onlyDigit(numStr)+ " Lakhs "+str; //Appends the word lakhs to it
}
}

if(places==6)
{
numStr=txter.substring(txter.length-9,txter.length-7)  //Substring for 7 place to 8 place of the string
if(numStr!="")
{
str=onlyDigit(numStr)+ " Crores "+str;        //Appends the word Crores
}
}

n=parseInt(n/10);
places++;
}
alert(str);
}




function onlyDigit(n)
{
//Arrays to store the string equivalent of the number to convert in words
var units=['','One','Two','Three','Four','Five','Six','Seven','Eight','Nine'];
var randomer=['','Eleven','Twelve','Thirteen','Fourteen','Fifteen','Sixteen','Seventeen','Eighteen','Nineteen'];
var tens=['','Ten','Twenty','Thirty','Forty','Fifty','Sixty','Seventy','Eighty','Ninety'];
var r=0;
var num=parseInt(n);
var str="";
var pl="";
var tenser="";
while(num>=1)
{
r=parseInt(num%10);
tenser=r+tenser;
if(tenser<=19 && tenser>10) //Logic for 10 to 19 numbers
{
str=randomer[tenser-10];
}
else
{
if(pl==0)        //If units place then call units array.
{
str=units[r];
}
else if(pl==1)    //If tens place then call tens array.
{
str=tens[r]+" "+str;
}
}
if(pl==2)        //If hundreds place then call units array.
{
str=units[r]+" Hundred "+str;
}

num=parseInt(num/10);
pl++;
}
return str;
}

</script>




<form name="fm" id="fm">

<input type="text"  name="txtinput" id="txtinput" maxlength="9" />
<input type="button" onclick="numToString(txtinput.value)" id="show" />

C program Number to Text 2 conversion

This C program will convert the number to words in tens and units place respectively. This is a part of Mumbai University MCA Colleges C programs MCA Sem 1
Out put as

Input:- 12345
Output:- twelve thousand three hundred fourty five


#include<stdio.h>

void pw(long,char[]);//function
char *unit[]={" "," one"," two"," three"," four"," five"," six"," seven","eight"," Nine"," ten"," eleven"," twelve"," thirteen"," fourteen","fifteen"," sixteen"," seventeen"," eighteen"," nineteen"};
char *ten[]={" "," "," twenty"," thirty"," forty"," fifty"," sixty","seventy"," eighty"," ninety"};

void main()
{
long n;
printf("Enter any 9 digit no: ");
scanf("%9ld",&n);
if(n<=0)
printf("Enter numbers greater than 0");
else
{
pw((n/10000000),"crore");//Will give either 1 or 2 digit answer
pw(((n/100000)%100),"lakh");//Will give either 1 or 2 digit answer
pw(((n/1000)%100),"thousand");//Will give either 1 or 2 digit answer
pw(((n/100)%10),"hundred");//Will always give 1 digit answer
pw((n%100)," ");////Will give always 2 digit answer
}
}


void pw(long n,char ch[])
{
(n>19)?printf("%s %s ",ten[n/10],unit[n%10]):printf("%s ",unit[n]);
/*This if condition will execute if n is greater than 0 and used to print crore, lakh, thousand and hundred
This is used so that if say we enter 12000 the answer must be "twelve thousand"
If you omit the if statement and simply write the print statement the output would be like
"twelve thousand hundred" which is not the right one
*/
if(n)
printf("%s ",ch);

void main()
{ clrscr();
float bs,ht,a,b,c,s;
float area;
int k;
printf("If you want to use base n height method then enter 1\n");
printf("If you want to use sides method then enter 2\n");
printf("Enter your choice:");
scanf("%d",&k);
switch(k)
{
case 1:
printf("Enter the base and the height of the triangle:");
scanf("%f%f",&bs,&ht);
area=0.5*bs*ht;
break;

case 2:
printf("Enter the three sides of the triangle:");
scanf("%f%f%f",&a,&b,&c);
s=(a+b+c)/2;
area=sqrt(s*(s-a)*(s-b)*(s-c));
break;
}
printf("The area of the triangle is:%f",area);
