# $results{$test}{"type"} is the result type, e.g. normal or complex. | |
# In the following description $platform, $type and $float are: | |
# - $platform is the used platform | |
# - $type is either "normal", "real" (for the real part of a complex number) | |
# or "imag" (for the imaginary part # of a complex number). | |
# - $float is either of float, ifloat, double, idouble, ldouble, ildouble; | |
# It represents the underlying floating point type (float, double or long | |
# double) and if inline functions (the leading i stands for inline) | |
# are used. | |
# $results{$test}{$platform}{$type}{$float} is defined and has a delta | |
# or 'fail' as value. | |
