Description

Emphasizes precision in numerically unstable or difficult problems. This parameter lets you specify to CPLEX that it should emphasize precision in numerically difficult or unstable problems, with consequent performance trade-offs in time and memory.

Value	bool	Symbol	Interactive	Meaning
0	false	CPX_OFF	no	Do not emphasize numerical precision; default
1	true	CPX_ON	yes	Exercise extreme caution in computation
