zero dollars

[dido4]

Q1.When should we use plural? Is the following way to tell when to use plural right?

If the number is not 1, every should be considered as plural, except uncountable nouns. (No matter it is zero or negative numbers.)
Ex. 1. The temperature is 0 degrees.
2. The temperature is -1 degrees.
3. I have lived here for 3.5 years.

Q2.Which is right?

1.I get zero dollar from my parents.
2.I get zero dollars from my parents.

I have to be a stickler for 1 and -1 degree (singular). All others can be plural, including zero degrees and fractions. If less than 1 degree, and stated as point 5 degrees (or point anything) then plural is fine; but as a proper fraction, such as one-half degree, it must be singular.

Except for point one degree because it also is ONE.
