6. What is the greatest integer function? + Example - Socratic
Oct 19, 2014 · Greatest integer function is denoted by [x]. This means, the greatest integer less than or equal to x. If x is an integer, [x]=x
Greatest integer function is denoted by [x]. This means, the greatest integer less than or equal to x. If x is an integer, [x]=x If x is a decimal number, then [x]= the integral part of x. Consider this example- [3.01]=3 This is because the greatest integer less than 3.01 is 3 similarly, [3.99]=3 [3.67]=3 Now, [3]=3 This is where the equality is used. Since, in this example x is an integer itself, the greatest integer less than or equal to x is x itself.

FAQs
What Is Greatest Integer Function? ›
The greatest integer function is a function that results in the integer nearer to the given real number. It is also called the step function. The greatest integer function rounds off the given number to the nearest integer.
What's the greatest integer function? ›The greatest integer function of x is a function that gives the largest integer which is less than or equal to x. This function is denoted by ⌊x⌋. The given number needs to be rounded off to the nearest integer that is less than or equal to the number itself.
What is the greatest integer function of 4? ›| Values of x (Domain) | ⌊x⌋ (Range) |
|---|---|
| 4 | ⌊4⌋ = 4 |
| 2.2 | ⌊2.2⌋ = 2 |
| −2.7 | ⌊−2.7⌋ = −3 |
| −7 | ⌊−7⌋ = −7 |
The greatest integer function takes any number and rounds it down to the nearest integer. For example, the number 6.3 would get rounded down to 6. Similarly, the number 7.9 would get rounded down to 7.
What is the difference between greatest integer function and least integer function? ›Notation. The least integer function greater than or equal to x is noted as ⌈x⌉ and is read as “integral value greater than x”. We use the notation ⌈x⌉ to refer to the “least integer that is greater than or equal to” in opposition to the notation ⌊x⌋ to refer to the greatest integer that is less than or equal to.
What is a greatest integer function in your own words? ›The greatest integer function is a function that takes an input and gives an output that is the greatest integer that is less than or equal to the input.
How do you solve the greatest integer function question? ›- Given, z = [y] and y = [x] − x, where [.] is the greatest integer function.
- If x is not an integer but positive,
- ⇒ x > 0 and x ∉ Z.
- ⇒ y = [x] − x = [x] − ([x] + {x})
- ⇒ y = -{x}
- Now given z = [y]
- Putting the value of y,
- ⇒ z =[-{x}]
- Proof of the greatest integer theorem: for every real number x there exists a unique greatest integer less than or equal to x.
- Integer part of a positive real number exists and is unique.
- Let x be a real number. ...
- Proof, that the floor and ceiling functions exist.
It is not required for a function to be either even or odd. It can be either even or odd, or none of the two. And there is no such thing as an even or odd greatest integer function.
Is the greatest integer function one to one? ›Hence, the greatest integer function is neither one-one nor onto.
Why is the greatest integer function not continuous? ›
Now, we will be using a test of continuity by checking if the left hand side limit is equal to the right hand side or not. Since L.H.L, R.H.L and the value of function at any integer $n\in $ are not equal therefore the greatest integer function is not continuous at integer points.
What is the greatest integer function in C++? ›C++ floor()
The floor() function in C++ returns the largest possible integer value which is less than or equal to the given argument. It is defined in the cmath header file.
The Greatest Integer Function [X] denotes an integral part of the real number x that is the closest and smallest integer to x. It's also called the X-floor. [x]=the largest integer less than or equal to x.
How do you solve greatest integer function equations? ›- Given, z = [y] and y = [x] − x, where [.] is the greatest integer function.
- If x is not an integer but positive,
- ⇒ x > 0 and x ∉ Z.
- ⇒ y = [x] − x = [x] − ([x] + {x})
- ⇒ y = -{x}
