Switching between float and integer types (if it’s supported by the module)
is done in the Signal Type property of the module:
A module set to integer type will process the input values as integers and
produce integer output values. You can tell that a module is in integer state
by the fact that its signal inputs and outputs look different:
There is no such thing as default signal type for macros. The reason is that
normally you wouldn’t build structures that process integers in exactly the
same way as structures processing floats and vice versa (although you might
for some relatively simple structures).
Integer signals can be freely interconnected with floats, but the wires
created between different type signals will perform signal conversion,
which can use a certain amount of CPU. At the time of this writing,
the extra CPU usage is somewhat noticeable on PCs and quite significant
on Macs. The OBC connections of float and integer types are not
compatible with each other, of course.
There can also be information loss during such conversions. In particular,
large integers cannot be precisely represented by floats, and
obviously, floats cannot be precisely represented by integers. Large
floats (larger than the largest representable integer) cannot be represented
as integers at all, in which case the result of the conversion
in undefined. During float-to-integer conversion, the values will be
rounded approximately to the nearest integer. We say approximately
because the result of rounding 0.5 can be either 0 or 1, although you
can rely on the fact that 0.49 will be rounded to 0, and 0.51 to 1.
