Converts a
CopyC#
double
 value to a sortable signed
CopyC#
long
. The value is converted by getting their IEEE 754 floating-point "double format" bit layout and then some bits are swapped, to be able to compare the result as long. By this the precision is not reduced, but the value can easily used as a long.
