# is a maximal error of a function or a single test.
# $results{$test}{"type"} is the result type, e.g. normal or complex.
# $results{$test}{"has_ulps"} is set if deltas exist.
-# $results{$test}{"has_fails"} is set if exptected failures exist.
# In the following description $type and $float are:
# - $type is either "normal", "real" (for the real part of a complex number)
# or "imag" (for the imaginary part # of a complex number).
# 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}{$type}{"fail"}{$float} is defined and has a 1 if
-# the test is expected to fail
# $results{$test}{$type}{"ulp"}{$float} is defined and has a delta as value
