For B&W paper development not that critical. It is better to be a few degrees over than under. For B&W film development it is essential that you keep the temp +/-1/2 a degree.

For colour you have to be that bit more stringent, in fact fastidiously stringent +/- .5 of a degree or you will waste a lot of paper.
