Hi,

the major code changes are in `RandomSupport` in methods

checkRange(float,float)
checkRange(double,double)

where the checks are more tolerant, and in

boundedNextDouble(RandomGenerator,double,double)
boundedNextFloat(RandomGenerator,float,float)


that extend the accepted range. In case the range size overflows, the methods half the range, generate a value inside the reduced range and finally double the outcome.
