4 digit in rtf in EBS

Hi All,

I have the below 2 columns which are using to display 4 digits.

<IC_UNIT_ITEM_COST1>.471016779777030259745</IC_UNIT_ITEM_COST1>

<IC_UNIT_COST_DSP>0.4710</IC_UNIT_COST_DSP>

<IC_UNIT_ITEM_COST1>.673487745828909269513</IC_UNIT_ITEM_COST1>

<IC_UNIT_COST_DSP>0.6735</IC_UNIT_COST_DSP>

IC_UNIT_COST_DSP -- is a char type that is coming from the Flex field query used in the EBS report.

IC_UNIT_ITEM_COST1 -- is a number.

0.4710 -- displaying as 0.471, why it is not displaying 0.4710?

0.6735 -- displaying as 0.6735

my requirement is to display 4 digits.

Thank you
