hi friends i am running below code in PHP to sum up values, but it is giving wrong sum value, please check where is the problem
<?php
$total_amount=80;
$total_amount+=5.6;
$total_amount+=0;
$total_amount+=-101;
//echo $total_amount; //gives -15.4
$total_rec=-15.4;
//echo $total_rec; //it is -15.4
$total_bal_amount= $total_amount-$total_rec;
echo $total_bal_amount; // gives -5.3290705182008E-15, it should give -30.8
?>
it is giving correct sum values in excel
