Synopses

Declared in <mp‐units/framework/quantity_point.h>

Returns the numerical value of this quantity point on the scale of another unit, implicitly convertible to rep.

Return Value

  • The numerical value expressed in u.

  • The numerical value expressed in u, measured from the default point origin.

Note

The return value should not be discarded.

Parameters
