Constants

The following mathematical and physical constants are available through the h module:

h.PI        3.14159265358979323846

h.E         2.71828182845904523536

h.GAMMA     0.57721566490153286060 (Euler)

h.DEG       57.29577951308232087680 (deg/radian)

h.PHI       1.61803398874989484820 (golden ratio)

h.FARADAY   96484.56 (coulombs/mole)

h.R         8.31441 (molar gas constant, joules/mole/deg-K)

Warning

Constants are not treated specially by the interpreter and may be changed with assignment statements.

The FARADAY is a bit different than the faraday of the units database. The faraday in a .mod mechanism is 96520.
