[fpc-pascal] mpcalc 7.3

[franco at solaris.polarhome.com]

A new version 7.3 of the unit mpcalc has been released and can be
downloaded from
http://www.polarhome.com/~franco/mpcalc-7.3.zip
or
http://spazioinwind.libero.it/frm/software/mpcalc-7.3.zip

Mpcalc provides multiprecision floating-point arithmetic up to 5000 digits.
It includes a set of elementary functions and some special functions.
I hope that it will be useful to someone.
In the package there is also a program to test the unit.
