constants. The default is currently 32 bits/single, which corresponds
to the old behaviour (constants which cannot be exactly represented
in the default/chosen precision will also still be automatically
upgraded to higher precision). Supported constructs:
* Command line switch -CF<x>
* Compiler directive {$MINFPCONSTPREC <x>}
whereby in both cases <x> can be default, 32 or 64. 80 is not supported
because there is no generic way to figure out whether the current target
actually supports 80 bit precision floating point calculations while
parsing the command line switches (pbestreal can still change in case of
win64 or -Cfsse2)
