Can you check why im off a little when calculating inputFile size?

for example when i upload a file that is 4.89 KB according to windows file properties, my output below gives me 4.74 KB. Its always real close and a little under.

 

 

String s = Document.body.toString();

Decimal byteCount = s.length();

Decimal kb_dec = byteCount / 1000;
Decimal kb_divDec = byteCount.divide(1000, 2, System.RoundingMode.UP);
	   			
double mb = kb_dec / 1000;
Decimal mb_divDec = kb_dec.divide(1000, 2, System.RoundingMode.UP);
	   			
ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.Info,'The image size is... ' +mb_divDec +' MBs, ' +kb_divDec+' KBs, '+byteCount+' bytes.'));

1KB is 1024 bytes, not 1000 bytes. (unless you manufacture disk drives)

Thank you SimonF. i also couldnt get it right until using body.size() instead of getting the string length() of the body.

 

 

Decimal byteCount = Attachment.body.size();

Decimal kb_dec = byteCount / 1024;
Decimal kb_divDec = byteCount.divide(1024, 1, System.RoundingMode.UP);
	   			
Decimal mb = kb_dec / 1024;
Decimal mb_divDec = kb_dec.divide(1024, 1, System.RoundingMode.UP);
	   			
ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.Info,'The image size is... ' +mb_divDec +' MBs, ' +kb_divDec+' KBs, '+byteCount+' bytes.'));
