Take the absolute value and show the original number

I want to use [rangemap] to display these numbers. But not all of these numbers are positive integer. So I have to take the absolute value. The question is how could I show the original number in rangemap?

example:

...|eval abs(num1) as use_num1 |rangemap field=use_num1 low=0-500 elevated=501-800 severe=801-10000000000

<module name="SingleValue">
    <param name="field">use_num1</param>
    <param name="classField">range</param>
  </module>

How could I show the original number in the SingleValue?

My English is poor.I hope you can understand what i mean. =) Thanks a lot.

The eval expession should look like:

..|eval use_num1=abs(num1) | ...

and to show the original number, you just have to use in the field option of the SingleValue module:

  <module name="SingleValue">
    <param name="field">num1</param>
    <param name="classField">range</param>
  </module>
