[SalesForce] Round a double value up to two decimal places

I have issue that I want to round the double data type to two decimal places.
I am writing the below apex code to do that but not working.

public Double APR_system_Volume_with_Racking_m3_Annual{get;set;}

APR_system_Volume_with_Racking_m3_Annual = ((dBBU_in_MBU * dTotal_Volume_BBU_m3) + dTotal_Volume_MBU_m3)* dMBU; 
      i = APR_system_Volume_with_Racking_m3_Annual * 10;
      APR_system_Volume_with_Racking_m3_Annual = Math.round(i);
      APR_system_Volume_with_Racking_m3_Annual = APR_system_Volume_with_Racking_m3_Annual /10;

Still my variable APR_system_Volume_with_Racking_m3_Annual showing value like 33737.670000000006 in my visual force page. I want to format that value in apex not in visual force outputtext formatting like

<apexutputText value="{0, number, 000,000.00}">
       <apexaram value="{!Account.AnnualRevenue}" />
</apexutputText>

In Apex try the following code. I hope this should work.

Decimal annualRevenue= 0;
annualRevenue= <Calculate your value>;
Account.AnnualRevenue = annualRevenue.SetScale(2); // set the result to 2 decimal places

[SalesForce] Round a Decimal to two decimal places

I don't think it gets more concise than this:

Decimal toround = 3.14159265;
Decimal rounded = toround.setScale(2);
system.debug(rounded);

What's nice about this one is you can use the setScale overload that lets you specify the rounding mode you want to use.

Decimal toround = 3.14159265;
Decimal rounded = toRound.setScale(2, RoundingMode.HALF_UP);
system.debug(rounded);

In this case - I think you'll want the HALF_UP rounding mode. It's the traditional round to nearest, but round .5 up.

[SalesForce] Round off an apex variable upto two decimal places

Keeping everything in visualforce here, there is a function to do precisely what you're looking for, ROUND.

It appears about half-way down the documentation page on visualforce functions

ROUND
Returns the nearest number to a number you specify, constraining the new number by a specified number of digits.
ROUND(number, num_digits) and replace number with the field or expression you want rounded; replace num_digits with the number of decimal places you want to consider when rounding.

An example of usage:

<!-- 20/3 = 6.6666... rounding to 2 decimal places should result in 6.67 -->
<apex:variable var="myVar" value="{!ROUND(20/3, 2)}"/>
