# - $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;

|
# double) and if inline functions (the leading i stands for inline)
|
|
# are used.
|
|
# $results{$test}{$platform}{$type}{$float} is defined and has a delta
