Challenges with ColdFusion's floating point calculations

I am encountering an issue with my program where it is not displaying two decimal points properly. For example, when I enter 140.00, it shows as 140.0. Strangely, if I enter 140.15, it displays correctly as 140.15. It seems to consistently drop the zero. Below is the code snippet that I suspect needs modification. Any assistance in resolving this would be greatly appreciated.

<cfinput type="Text" name="HourlyRate" 
       value="0.00" 
       required="Yes" 
       validate="float"              
       message="A Default Hourly Rate is required...."
       class="inputText200" size="8">**

Alternatively, here is another code snippet:

<input type="text" name="Rate" 
       <cfif #getHourlyForm.Rate# neq ""> value="#getHourlyForm.Rate#"</cfif> />

Answer №1

The issue arises from the fact that when you insert content into the "value" attribute, it is essentially treated as HTML code being rendered.

This results in CF converting your numerical values into string representations during the HTML generation process.

For a solution, I recommend checking out the NumberFormat function mentioned here. This function allows you to specify how CF should format and output the content instead of relying on its default behavior.

<tr colspan="2">
        <td class="tdDescription"> Rate Per Hour </td>
        <td><input type="text" name="Rate" class="inputText350" <cfif getHourlyForm.Rate neq ""> value="#NumberFormat(getHourlyForm.Rate,"9.99")#"</cfif>/></td>
</tr>
