So this means when a pot of water has just started to boil, the contents are exactly 100 degrees (give or take a smidge)?
I'm facepalming that you didn't mention pressure of 1 atm, but yes, you have it right.

Anything dissolved or suspended in the water will have an effect, but in general, these effects are not too very drastic. You have to add an insane amount of salt (as far as taste is concerned) to water to increase it's boiling point by even a degree.
