Detailed Description

template<class T, class Ret>
struct units::traits::is_nonlinear_scale< T, Ret >

Trait which tests that class T meets the requirements for a non-linear scale.

A non-linear scale must:

• be default constructible
• have an operator() member which returns the non-linear value stored in the scale
• have an accessible m_value member type which stores the linearized value in the scale.

Linear/nonlinear scales are used by units::unit to store values and scale them if they represent things like dB.
