Simple perl help - converting numbers

Hi friends,

I'm very new to perl and got some requirement.
I've input numbers which has size of 17 characters [including +/- sign and .] like below:

Code:
-22500.0000000000
58750.00000000000
4944.000000000000
-900.000000000000
272.0000000000000

I need to convert these numbers from negative to positive and positive to negative. After the conversion again I need to get 17 characters.
After some googling below is the part of the script I've written.

Code:
$num = -22500.0000000000
$num = sprintf("%17f" - $num);

But this is not giving me the desired output. My requirement to the above numbers should be as below:

Code:
22500.00000000000
-58750.0000000000
-4944.00000000000
900.0000000000000
-272.000000000000

Could any one help me please?

Thanks and Regards,
Mysore Ganapati
