I would like to know how to keep the variable double with 2 houses after the comma. Below I have an example, when transforming a String into double if it has values after the point is kept the 2 houses, however if it is only zeros, no.
"10.01" => 10.01
"10.00" => 10.0 //Gostaria do resultado 10.00
You can do this:
String resultado = String.format("%.2f", valor);
Or you can also do this:
double numero= 10.00;
DecimalFormat formato = new DecimalFormat("#.##");
numero = Double.valueOf(formato.format(numero));
Also use .setscale()
BigDecimal bd = new BigDecimal(< tipo >);
bd.setscale(< qtdCasas >);
