set double format with 2 decimal places [duplicate]

Question

This question already has answers here:

Round a double to 2 decimal places [duplicate] (13 answers)

Closed 8 years ago.

I have a short equation:

double compute,computed2;

compute=getminutes/60;

where getminutes is int and I want to set the equivalent of compute with 2 decimal places. 0.00 how can I format the equivalent with 2 decimal places?

Example:

compute=45/60 it should be 0.75 

Here is my work:

DecimalFormat df2 = new DecimalFormat("00.00000");
double computed,computed2 = 00.000;

computed=60/getitbyminutes;
df2.format(computed);
computed2=computed-8;
df2.format(computed2);

System.out.printf("%1$.2f",computed);
System.out.println();
System.out.printf("%1$.2f",computed2);

the out put will be just like :

1.00
7.00 

Answer 1

Cast it to Double

compute=(Double)getminutes/60;

and then use DecimalFormat as mentioned by Peter.

Answer 2

Just format the output the right way:

double d = 1.234567;
DecimalFormat df = new DecimalFormat("#.##");
System.out.print(df.format(d));
