No, it´s not floating point it´s the easy datatype "float"....for example:
float number = -2000;?

If you mean floating point, like IEEE 754 then yes.The first bit is what
decides the sign. If it's set then the number is negative, if reset then the
opposite.

If you have some kind of bastardized compiler it might be better to
write:
float number = -2000.;
Also consider using "double".

What is an "easy datatype"? What is a "bastardized compiler"? Why should it
be double?

I have not the slightest; I didn't write that. I assume it's a translation
of "simple" from another language than English.
>What is a "bastardized compiler"?
One that does not conform substantially to the
ISO/IEC 9899:1999 (E) standard. The "." I suggested prevents conversions
from taking place, so it matters less.
>Why should it be double?
There can be unholy interactions between the linked FP libraries
and the data type selected, IME. Check carefully that everything is
consistent.

I suspect your problem is that you are using "float" to describe the value
from the ADC, when it should be "integer". If it is not properly type cast
then you will end up with funny things happening.
