    Factor const& t) noexcept;

Description

Computes the linear interpolation between a and b, if the parameter t is inside [0, 1) (the linear extrapolation otherwise), i.e. the result of a + t(b − a) with accounting for floating‐point calculation imprecision.

Parameters

Name

Description

A quantity point
