Introduction

#include <xo/unit/bpu.hpp>

A xo::qty::bpu (aka “basis power unit”) represents a rational (usually integer) power of a Basis Unit.

For example:

object mm3<<bpu>>
mm3 : native_dim = dim::distance
mm3 : scalefactor = 1/1000
mm3 : power = 3/1 — representation for cubic millimeters

object vol<<bpu>>
vol : native_dim = dim::time
vol : scalefactor = 365*24*3600
vol : power = -1/2 — representation for annual (365-day) volatility

bpu is intended as an implementation-level abstraction. Application code will normally interact with the more-general scaled_unit instead of bpu.

Class
