The simplest way to represent an integer argument is
``NumberValue(step=1, ndecimals=0)``.
:param unit: A string representing the unit of the value, for user
interface (UI) purposes.
:param scale: The scale of value for UI purposes. The displayed value is
divided by the scale.
For arguments with units, use both the unit parameter (a string for
display) and the scale parameter (a numerical scale for experiments).
For example, ``NumberValue(1, unit="ms", scale=1*ms)`` will display as
1 ms in the GUI window because of the unit setting, and appear as the
numerical value 0.001 in the code because of the scale setting.
:param unit: A string representing the unit of the value, for display
purposes only.
:param scale: A numerical scaling factor by which the displayed value is
multiplied when referenced in the experiment.
:param step: The step with which the value should be modified by up/down
buttons in a UI. The default is the scale divided by 10.
:param min: The minimum value of the argument.
