Zero-point
What this part means
The integer code that stands for the real value zero. If Z = 10, then q = 10 decodes to r = 0 exactly. It shifts the integer code range left or right relative to real zero.
Its job in the formula
Z is one of the signed contributions combined to compute the quantity on the left.

The passage around this formula
…made this practical for commodity hardware is an affine mapping between a real value and its stored integer, . where r is the real-valued number, q is the stored integer, S > 0 is a scale factor, and Z is an integer zero-point chosen so that real zero maps exactly onto a representable integer — a detail that matters because operations like zero-padding and ReLU depend on zero being represented without rounding error. Jacob and colleagues showed that with this scheme, matrix multiplications and…
Learn the underlying idea
The zero-point is the integer code chosen to mean the real value zero.
