22 # In the following description $platform, $type and $float are:
23 # - $platform is the used platform
24 # - $type is either "normal", "real" (for the real part of a complex number)
25 # or "imag" (for the imaginary part # of a complex number).
26 # - $float is either of float, ifloat, double, idouble, ldouble, ildouble;
27 # It represents the underlying floating point type (float, double or long
28 # double) and if inline functions (the leading i stands for inline)
30 # $results{$test}{$platform}{$type}{$float} is defined and has a delta
