division has higher precedence than addition, so 1/4 is calculated first,
and the result is then added to 0.1.

and as I've already explained, 1/4 is an integer division, so the result
is rounded down to the the nearest integer (0).  in other words, your
expression boils down to

    0.1 + 0

which is 0.1 [1].

the precedence order is explained here:
