hi all,

How to divide two numbers ?

I try this :

float var1=0.0
var1=$((2.4 + 1.4))
echo $var1

return 3.800000000e+00 good !!

but

float var1=0.0
var1=$((3 / 2)) 
echo $var1

return 1.000000000e+00 not good ! :(

and how to format the output of $var1 ?
(i want a number like 95.3)

Thank you very much
