atan2(a,b) should be an approximate number (float or bfloat) whenever one of the arguments is approximate and the other is either approximate or an exact number.

This is not currently true. All the following give results involving %PI: atan2(-1.0,-1), atan2(-1.0b0,-1.0), atan2(- 2/3,-1.0b0) etc.

The attached code fixes this.
