Question

• How can i round float to nearest whole number and then convert into double?
• What is the best method to achieve this ?

Thanks,

Answer 1

double myRoundedDoubleValue = Math.round(myValue);

Answer 2

Try it this way:

public static void main(String arguments[]) {
    float myValue=5.1824203f;
    int rounded = Math.round(myValue);
    System.out.println("as int: " + rounded);
    float floated = (float) rounded;
    System.out.println("as float: " + floated);
}

OUTPUT:

as int: 5
as float: 5.0

Answer 3

float myValue=5.1824203f;
double rounded = Math.round(myValue);

Please also note the difference in the float myValue initialization.
