Constants
~~~~~~~~~
The following mathematical and physical constants are built-in:
.. code-block::
none
"PI", 3.14159265358979323846,
"E", 2.71828182845904523536,
"GAMMA",0.57721566490153286060, /* Euler */
"DEG", 57.29577951308232087680, /* deg/radian */
"PHI", 1.61803398874989484820, /* golden ratio */
"FARADAY", 96484.56, /*coulombs/mole*/
"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 :file:`.mod` mechanism is 96520.
