CoinRelFltEq

Equality to a scaled (relative) tolerance.

Equality to a scaled (relative) tolerance.

Description

Operands are considered equal if their difference is within a scaled epsilon calculated as epsilon_*(1+max(|f1|,|f2|)). This is preferred over absolute tolerance when comparing values that span many orders of magnitude.
