holding values from other functions?

noob at C (3)
Ok so im confused because when I call a function on its own the decimal is kept, but when I call the display function it no longer displays the correct decimal just .00
I put the code below, i only included one function because otherwise it would be a lengthy post. Any help would be appreciated even if it is just a suggested search term to go read the info i am missing.

I'm not sure I understand. Could you provide an example of the actual program output and then the expected or required output for comparison.

(use the [output]results here[/output] tags to display properly formatted.

yeah, so

basically i ask the user for inputs to make a budget and then display the inputs in a table of sorts
my initial function should look like this :

Your actual taxes withheld: 502.12 (user inputs- 502.12)

this works correctly.

but then in the display() it makes a table like this

budgeted actual
====== ======
502.00 502.00


the issue is that it drops the .12 and i cant figure out why.

// int getActualTax()
double getActualTax()
{
   double actTaxesWithheld ;
   cout << "\tYour actual taxes withheld: " ;
   cin >> actTaxesWithheld ;
   return actTaxesWithheld ;
}
