# COntvert and round off float

HOw would I round off a float? For example:

float numA = 26.07;
float numB = 40.00;
float answC;

answC = numA/numB * 100;

I want to have answC hold 65 not 65.175

That didn't work for me! Also I don't care if  answC holds the final value or not.

or you can declare ansWC as an int

int answC ;

answC = (int)(numA/numB * 100);

oops should be ...

BigDecimal answCdec=new BigDecimal(answC);
answC= answCdec.setScale(0).doubleValue();

double numA = 26.07;
double numB = 40.00;
int answC;
answC = (int) Math.floor(numA/numB * 100);  // Note: return type is double. convert it to int (or float)
System.out.println("Answer C is ->" + answC);

If you want to declare the numbers as float, you should do:

float numA = (float) 26.07;  // value is double, convert it to float.
float numB = (float) 40.00; // value is double, convert it to float.
int answC;
answC = (int) Math.floor(numA/numB * 100);
System.out.println("Answer C is ->" + answC);
