Do I change the output voltage of a transformer if I change the input voltage?

I want to buy a transformer:

The output voltage is: 34V.

But it says:

"They are specially designed to work on all standard 115V or 230V at 50Hz or 60Hz."

I live in the US, New England and the wall eletricity is 120V not 115V. So should I adjust the conversion factor?

Output Voltage = 34V * 120V / 115V = 35.48V

If this isn't how I should do this please explain what the error in my thinking is because I need to understand this.

If you want to check out the transformer I'm looking at it's:

Code: Electrical Characteristics

Outputs 2x

Power 200VA

Output Voltage Current

34V 3.0A

Code:The 200VA toroidal transformers are commonly used in the noise sensitive equipment, high-end audio products, stepper motor supply, or servo motor supply. They are specially designed to work on all standard 115V or 230V at 50Hz or 60Hz. These transformers have heavier gauge wires then the normal requirement to avoid the copper lost during the full power output. The dielectric test is more than 3500V in between primary and secondary coils. Please see the test data for short circuit and open circuit. In most of the cases, this transformer can be output 20% more power from its rating at 60Hz power source without any problem. This transformer comes with 2 rubber pads and all mounting hardware.
