bc calculate problem

Hi ,

this is the first time i use bc to calculate and i would have decimal result , i use the following :

toto=400;scale=1 echo $toto / 1000|bc

scale to adjust the numbers after the command would have in this case 0.4 as result and i wonder why i have always 0 as result.

Somebody can help ?

thanks

Christian
