Enumeration Type Documentation

SCIP_IsFpRepresentable

enum SCIP_IsFpRepresentable

information if a rational is exactly representable as a floating point number

Enumerator
SCIP_ISFPREPRESENTABLE_UNKNOWN	representability is unknown
SCIP_ISFPREPRESENTABLE_TRUE	is representable
SCIP_ISFPREPRESENTABLE_FALSE	is not representable

Definition at line 46 of file type_rational.h.

SCIP_RoundModeRational

enum SCIP_RoundModeRational

defines the possible rounding direction for a rational number, when converting to a double

Enumerator
SCIP_R_ROUND_DOWNWARDS	always round to nearest smaller double
SCIP_R_ROUND_UPWARDS	always round to nearest larger double
SCIP_R_ROUND_NEAREST	always round to nearest double
