NO
-3.1 and 3.1 are both Real numbers, the minus or positive sign doesn't make a difference.
A whole number like the number of matches you can lay on a table. You can lay as many as you want or zero matches, but you can't lay down a negative match. Notice I am not allowing you to break a match and lay down a portion of one.
Whole numbers are the set whose members are:
(0,1,2,3,4...)
An integer is a whole number it is a number of the following set:
(...-4,-3,-2,-1,0,1,2,3,4...)
This doesn't include fractions or any parts of a number.
The set of Real Numbers includes all the numbers in between. The set whose members are: (,,,-1.0.1...) and all the numbers in between.
Use the number line to answer your question: http://en.wikipedia.org/wiki/Number_line
The number line runs from 0 to negative infinity and from 0 to positive infinity it includes all the numbers in between.
Irrational numbers are those numbers that aren't on the number line like the square root of a negative number. These are the weird numbers that have no representation in the real world.

Why don't you just ask "What is an integer"? Because if you knew what the definition of an integer was, you'd know the answer.

No, this is not an interger. An interger is a whole number positive or negative. -3.1 would be a rational number though.

No. It must not have fractional part in order to be an integer.
