# ISNUMBER

## Syntax of the ISNUMBER function

The syntax of the ISNUMBER function is straightforward. It takes only one argument, which is the value to be checked. The syntax is as follows:

ISNUMBER(value)

``` The value argument can be a number, a reference to a cell that contains a number, or a calculation that evaluates to a number. How to use the ISNUMBER function in Power BI The ISNUMBER function can be used in a number of ways in Power BI. In this section, we will explore some of the most common ways to use the ISNUMBER function. Checking for numbers in a column One of the most common use cases for the ISNUMBER function is to check whether a column contains only numbers. This can be useful when working with data that is not well-formatted or when analyzing data from different sources. To check whether a column contains only numbers, you can use the following formula: ```

=IF(COUNTBLANK(column)=0,IF(COUNTIF(column,”❱=”&0)=COUNTA(column),”All Numbers”,”Mixed”), “Blank”)

``` This formula checks whether the column is blank, contains only numbers, or contains a mix of numbers and other values. Converting text to numbers Another use case for the ISNUMBER function is to convert text values to numbers. Power BI sometimes treats text values as strings, which can cause problems when performing calculations or creating visualizations. To convert text values to numbers, you can use the following formula: ```

=IF(ISNUMBER(VALUE(text)),VALUE(text),””)

``` This formula checks whether the text value is a number and converts it to a number if it is. If the text value is not a number, the formula returns an empty string. Filtering by numbers You can also use the ISNUMBER function to filter data by numbers. For example, you may want to filter a column to show only values that are greater than a certain number. To do this, you can use the following formula: ```

=FILTER(column,ISNUMBER(column),column❱=number)

``` This formula filters the column to show only values that are numbers and are greater than or equal to the specified number. The ISNUMBER function is a useful tool in Power BI that allows you to check whether a value is a number or not. It can be used in a variety of ways, including checking for numbers in a column, converting text values to numbers, and filtering data by numbers. By using the ISNUMBER function, you can ensure that your data is properly formatted and ready for analysis and visualization.
