Config

Config is the global configuration singleton that controls all precision, calculation, and table-loading settings for a Lactuca session. Changes take effect immediately for all subsequent calculations in the same Python process; call reset() to restore factory defaults.

Decimal precision	decimals.*	Decimal Precision and Rounding
\(l_x\) interpolation	lx_interpolation ("linear" / "exponential")	lx Interpolation
