# How to use the isfinite method in Julia

Programming Bytes

### Overview

The isfinite() method can be used to check if the given value is a finite number or not.

### Syntax

isfinite(f) -> Bool
Julia isfinite function Syntax

### Parameter

This method takes the parameter  f which represents the value that is to be checked.

### Return value

This method returns true if the provided value is finite. Otherwise, false is returned.

### Code

The code below demonstrates how to use the isfinite method.

## find isfinite of 10 / 0
println( "isfinite(10 / 0) => $(isfinite(10 / 0))") ## find isfinite of 10 println( "isfinite(10) =>$(isfinite(10))")

## find isfinite of 0
println( "isfinite(0) => \$(isfinite(0))")
Using the isfinite method

### Explanation

In the code above, we do the following:

• Line 2: We use the isfinite method with (10/0) as an argument. Any non-zero value divided by 0 will produce an infinite value. So the isfinite(10/0) will return false.
• Line 5: We use the isfinite method with 10 as an argument. The isfinite(10)will return true because 10 is a finite value.
• Line 8: We use the isfinite method with 0 as an argument. The isfinite(0)will return true because 0 is a finite value.
