Fix numerical constants
Change the decimal form of numerical constants to the necessaryand sufficient precision for the input of 8-byte IEEE floatingpoint numbers.Since the x87 floating point math that is still in use for 32 bitx86 builds uses 10-byte floats internally, which results in smalldifferences for some input (and also to sometimes seeminglyunpredictable results with respect to compiler options),some more changes were necessary:- change sellipse_check()- reduce floating point output for Spoint tests by 2 decimal digits in order to offset rounding problems for HMS input- add missing set_sphere_output_precision() to aggregate data test
