 Created a simple BPA to test a function which is not working in the way it is supposed to be

We tried to do 2108.39+2108.39+1330.8+189.83+4561.12+480.55 and the desired result should be 10779.08, but we get a result of 10779.079999999998 when using the sum function

A simple BPA with a step type of Edit data with the steps as below:

move 'true' to "parm/+listofpay/use";
move '2108.39' to "parm/listofpay[last()]/amt";
move 'true' to "parm/+listofpay/use";
move '2108.39' to "parm/listofpay[last()]/amt";
move 'true' to "parm/+listofpay/use";
move '1330.8' to "parm/listofpay[last()]/amt";
move 'true' to "parm/+listofpay/use";
move '189.83' to "parm/listofpay[last()]/amt";
move 'true' to "parm/+listofpay/use";
move '4561.12' to "parm/listofpay[last()]/amt";
move 'true' to "parm/+listofpay/use";
move '480.55' to "parm/listofpay[last()]/amt";
//move "sum(parm/listofpay[use='true']/amt)" to "parm/totamt";
move "sum(parm/listofpay/amt)" to "parm/totamt";

The Schema Set up is as below:
<totamt dataType="number"/>
<listofpay type="list">
<amt dataType="number"/>
<use dataType="boolean"/>

When we try to print the parm/totamt it is printing it as 10779.079999999998, though all the schema nodes are declared as type number, we get these strange results.
