AMD hudson: Truncate the float point number to integer

From awk info:
    because all numbers in `awk' are floating-point numbers, the result is
    _not_ rounded to an integer--`3 / 4' has the value 0.75.

For some system, the awk command
    printf("%c", 0.1);
    produces nothing, instead of 0. We need to convert the floating to
    integer. int(X) is an awk built-in function.
