An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043.
Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4… Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… All integers belong to the rational numbers.
Types of Integers
Integers come in three types: Zero (0) Positive Integers (Natural numbers) Negative Integers (Additive inverse of Natural Numbers)
Integers: These are of four types: byte , short , int , long . It is important to note that these are signed positive and negative values. Signed integers are stored in a computer using 2's complement.
Some of the examples of non-integers include decimals, fractions, and imaginary numbers.
Lesson Summary. The set of integers includes zero, negative and positive numbers without any decimal or fractional parts. They are numbers that represent whole things without pieces either above (positive) or below (negative) a standard value. They also include zero.
Key idea: Like whole numbers, integers don't include fractions or decimals.
Every integer is not a whole number . Hence , the given statement is false . So, the correct answer is “FALSE”. Note: An integer can be positive or negative whereas whole numbers are only positive .
Yes, zero is an integer.
(i) The smallest integer is zero.
All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.
Integers are positive numbers, negative numbers and zero. This means numbers like 0,1,2,3 as well as -1, -2, -3, are integers. Integers do not have any added parts such as decimals or fractions. Therefore, numbers with fractions like 3 1/2 or decimals like -7.5 are NOT integers.
So, the positive integers list is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, ..... and so on.
The opposite of 3 is -3.
A negative integer is a whole number that has value less than zero. Negative integers are normally whole numbers, for example, -3, -5, -8, -10 etc.
Q: How should I decide which integer type to use? A: If you might need large values (above 32,767 or below -32,767), use long. Otherwise, if space is very important (i.e. if there are large arrays or many structures), use short. Otherwise, use int.
Non-Negative Integers = { 0, 1, 2, 3, 4, ... } (includes zero, see?)
RULE 1: The product of a positive integer and a negative integer is negative. RULE 2: The product of two positive integers is positive. RULE 3: The product of two negative integers is positive. RULE 1: The quotient of a positive integer and a negative integer is negative.
