Julia | checkbounds() function with examples Last Updated : 12 Jul, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report The checkbounds() is an inbuilt function in julia which is used to return true if the given index value lies within the bounds of the given array, otherwise returns false. Syntax: checkbounds(Bool, Array, Index) Parameters: This function accepts three parameters which are illustrated below:- Bool: This says that this function will return boolean values as output. Array: It is the given array with bounds Index: It is the index value which is going to be calculated either it lies in the array bounds or not. Returns: It returns the value true if the index value lies in the array bounds else false. Below are some codes which illustrate the above function: Example #1: Python # Julia Program for illustration of # checkbounds() function # Initializing an array from 1 to 10 A = rand(1, 10); # Initializing a index value of 5 Index = 5 # Calling the checkbounds() function A = checkbounds(Bool, A, Index) # Getting the value true or false println(A) Output: true Example #2: Python # Julia Program for illustration of # checkbounds() function # Initializing a range from 1 to 10 A = rand(1, 10); # Initializing a index value of 15 Index = 15 # Calling the checkbounds() function A = checkbounds(Bool, A, Index) # Getting the value true or false println(A) Output: false Comment More infoAdvertise with us Next Article Julia - Call Java Functions K Kanchan_Ray Follow Improve Article Tags : Julia Similar Reads Julia | checkindex() function with examples The checkindex() is an inbuilt function in julia which is used to return true if the given index value lies within the range, otherwise returns false.

Julia was designed to be used in a wide range of applications, including numerical computing, data science, machine learning, and parallel computing.

These keywords can not be used as a variable name, doing the same will stop the execution process and an error will be raised. 'if' keyword in Julia is used to evaluate a condition. If the condition is t 2 min read Working with Date and Time in Julia Julia provides a library to use Dates for dealing with date and time. The Dates module comes inbuilt with the Julia we just need to import it in order to use it. Now we need to prefix every function with an explicit type Dates, e.g Dates.Date.
