Rounding – off difference

Dear John,

What is the examiners policy on rounding differences.

I.E : My answer for a question where :

Yield Variance : 9901 F
Mix Variance : 5829 A

Examiner answer:
Yield Variance : 9898.69
Mix Variance : 5826.69 A

Would i get full marks for my answer or will i be penalized for this slight difference. As there is not specification in the question, does the examiner expect you to work with 2 decimal places or can i just round to the nearest whole number for neatness in calculations?

Thanks.
