"Ramanujan's Constant (e^(pi*sqrt(163))) And Its Cousins"

How do we explain the numerical phenomena:

    e^(pi*sqrt(163)) ~ 640320^3 + 743.99999999999925...
    e^(pi*sqrt(37)) ~ 2^6(6+sqrt(37))^6 - 24.00000138...
    e^(pi*sqrt(130)) ~ 12^4(323+40*sqrt(65))^4 - 104.0000000000012...

Are these just flukes or do these numbers fit in a pattern?  It turns out the answer is the latter.  Quadratic powers sqrt(
d) of Gelfond's constant e^pi, numbers which are transcendental, can be closely approximated by certain algebraic numbers.  The "excess" of the approximation is also predictable, and approaches various integer values the larger d becomes.

Not to mention that it has an interesting connection to pi formulas and the Monster group...
