Starnge bug :

$tva=1.005+0.005-0.005;
echo number_format($tva,2);

outputs 1.00 instead of 1.01

but :

$tva=1.005+(0.005-0.005);
echo number_format($tva,2);

outputs 1.01 what is correct but this should not be influenced by the brackets.

and :

$tva=1.05+0.05-0.05;
echo number_format($tva,1);

outputs 1.1 what is correct

Thankx for reply
Regards,
Lorang Jacques
