How to call decimal to currency format in controller into vf page?
You may change code as below: public String getAmt() {
String sAmt = '', sTemp ='', sLast='';
Decimal dAmt = Opp.Amount;
sAmt = FormulateAmountInString(dAmt);
return sAmt;
}
public string FormulateAmountInString(Decimal dAmt) {
String sAmt = '', sTemp ='', sLast='';
If(dAmt > 1000) {
sAmt = String.valueOf(dAmt);
sLast = sAmt.right(6);
sTemp = sAmt.left(sAmt.length() - 6);
if(sTemp.length() > 2) {
while( sTemp.length()/2 > 0) {
sLast = sTemp.right(2)+ ',' + sLast;
sTemp = sTemp.Left(sTemp.length() -2);
}
}
sAmt = sTemp + ',' + sLast;
//sAmt = sAmt + '.' + String.valueOf(dAmt).substringAfter('.');
} else {
sAmt = String.valueOf(dAmt);
}
return sAmt;
}
