How to format double in Salesforce Apex

Question

I want to display double in format such as "12.30" but it display "12.0" in salesforce apex. can any one help me?

Answer 1

VisualForce uses the java.text.MessageFormat conventions for formatting. Here's an example. Replace the MyDouble variable with your own.

<apex:outputText value="{0,number,0.00}" >
    <apex:param value="{!MyDouble}" />
</apex:outputText>

Answer 2

You can cast the 12.30 as an int and then cast it back to double. Casting it to an int truncates the fraction.

double i = 10.345;
system.debug('this is i '+ i);
system.debug('this is i after fixing '+ (double)(integer)i);

gives:

10:04:26.129 (129990000)|USER_DEBUG|[16]|DEBUG|this is i 10.345
10:04:26.130 (130080000)|USER_DEBUG|[17]|DEBUG|this is i after fixing 10.0

Answer 3

When you are creating a field then we have to define it's decimal places. Try specifying that decimal number to 2. It will work.
