# Information about tests are stored in: %results

# $results{$test}{"kind"} is either "fct" or "test" and flags whether this
26 
# is a maximal error of a function or a single test.
27 
# $results{$test}{"type"} is the result type, e.g. normal or complex.
28 
# $results{$test}{"has_ulps"} is set if deltas exist.
29 
# $results{$test}{"has_fails"} is set if exptected failures exist.

# In the following description $type and $float are:
31 
# - $type is either "normal", "real" (for the real part of a complex number)
32 
#   or "imag" (for the imaginary part # of a complex number).
33 
# - $float is either of float, ifloat, double, idouble, ldouble, ildouble;
34 
#   It represents the underlying floating point type (float, double or long
35 
#   double) and if inline functions (the leading i stands for inline)
36 
#   are used.
37 
# $results{$test}{$type}{"fail"}{$float} is defined and has a 1 if
38 
# the test is expected to fail
39 
# $results{$test}{$type}{"ulp"}{$float} is defined and has a delta as value
