convert( expr, RealRange )

expression
The convert(expr, RealRange) function converts Complex ranges (see assume[parametric]) in expr into Real ranges.
Note: in Maple, by convention, when you say, for instance, z≤1, it is implicitly assumed that ℑ⁡z = 0.
z::ComplexRange⁡−1−I,1+I
convert⁡,RealRange
ℜ⁡z::−1,1,ℑ⁡z::−1,1
zinComplexRange⁡−∞⁢I,I
z∈ComplexRange⁡−∞⁢I,I
ℜ⁡z∈0,ℑ⁡z∈−∞,1
In turn, RealRanges as well as ComplexRanges can be converted into relations.

Note that when constructions such as z<a or z≤a are used, it is understood that z is real
