Make sure the variable is surrounded by *double* quotes!
*string="this:is:a:string"; IFS=: ; read foo bar moo cow <<< "$string"
*echo $foo $bar $moo $cow

+<pre>
+ bc <<<"2 + 2"
+ 4
+</pre>
+Note that, while bc(1) supports arbitrary precision, the default number of decimal points it displays is zero:
+<pre>
+ bc <<<"3 / 2"
+ 1
+</pre>
+To change this, set the "scale" variable to the number of decimal places you want to see:
+<pre>
+ bc <<<"scale = 3; 3 / 2"
+ 1.500
+</pre>
