◆ IFUNITS

#define IFUNITS {if (!UnitsOn) return;}

Definition at line 50 of file units.cpp.

◆ NRN_DYNAMIC_UNITS

#define NRN_DYNAMIC_UNITS 0

The strategy for dynamic units selection between Legacy and modern units is to maintain two complete tables respectively.

Legacy and modern in the nrnunits.lib.in file are distinquished by, e.g., 9.6485309+4 coul 96485.3321233100184 coul The reason for two complete tables, as opposed to a main table and several short legacy and modern tables, is that units are often defined in terms of modified units. eg, "R = (k-mole) (joule/degC)"

Nmodl, via the parser, uses only unit_pop, unit_mag, Unit_push, install_units, unit_div, and modl_units.

The issue of unit magnitude arises only when declaring a unit factor as in the gasconstant (R) above or with the equivalent "name = (unit) -> (unit)" syntax. If the magnitude difers between legacy and modern, then instead of emitting code like "static double FARADAY = 96485.3;\n" we can emit #define FARADAY nrnunit_FARADAY[nrnunit_use_legacy] static double nrnunit_FARADAY[2] = {96485.3321233100184, 96485.3};
