Type Conversion Errors (decimal to int)

[jonathan_rou]

Good afternoon,

I've run into some issues with the function int() while trying to convert a decimal number to an int.

Here's my example: 

I have an entity on CDS that has a field called "price" that is stored as a decimal number. 

However, simply calling int() on that field throws an error, specifically "Unable to process template language expressions in action 'Compose_2' inputs at line '1' and column '2595': 'The template language function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'."

I've tried to make the decimal a string and then convert, but that fails with a similar message. 

An example price would be 2819.23. I believe the issue is contained within the int() function but would love to hear any suggestions. Thank you!

If you review the Wokflow Definition Language documentation for Integer, please notice that int() requires a string:

int
Return the integer version for a string.
int('<value>')

So, your option is only really to "float" the decimal places via a variable or action. If the float value is in a variable:

substring(string(variables('VARIABLE_NAME')),0,add(indexof(string(variables('VARIABLE_NAME')),'.'),3))

If the float value is in an action:

substring(actionOutputs('ACTION_NAME'),0,add(indexof(actionOutputs('ACTION_NAME'),'.'),3))

Please see this previous post by @gamoraes  that explains the process in further detail. There is also a Currency and decimal format in Microsoft Flows idea currently "Under Review" that you may vote or comment on.

Hi @jonathan_rou ,

As you said, the price is float not integer.

So please take the float() for a try.

This code segment: substring(string(variables('VARIABLE_NAME')),0,add(indexof(string(variables('VARIABLE_NAME')),'.'),0)) worked to remove the decimal places from the decimal number. 

Thank you for your help.

Using the format number action makes converting the float/decimal to string easy then you just give its output to int()
