# How to use the isinteger method in Julia

Programming Bytes

## Overview

In Julia, the isinteger(x) method checks whether or not the given value is equal to an integer.

### Syntax

The syntax of the method is given below:

isinteger(x) -> Bool
Julia isinteger function Syntax

### Argument

x: This is the value that is to be checked.

### Return value

This method returns true if the provided value is numerically equal to an integer value. Otherwise, it returns false.

### Code

The code below demonstrates the use of the isinteger method:

## find isinteger of 3.0
println( "isinteger(3.0) => $(isinteger(3.0))") ## find isinteger of 10 println( "isinteger(10) =>$(isinteger(10))")

## find isinteger of 3.5
println( "isinteger(3.5) => \$(isinteger(3.5))")
Using the isinteger method

### Explanation

Line 2: We use the isinteger method with 3.0 as an argument. The isinteger(3.0) returns true.

Line 5: We use the isinteger method with 10 as an argument. The isinteger(10) returns true .

Line 8: We use the isinteger method with 3.5 as an argument. The isinteger(3.5) returns false because 3.5 is not an integer value.
