Expand Up @@ -18,7 +18,7 @@ This PEP proposes implementing the standard format specifiers ``.`` and ``z`` of

``z`` ("modulo-precision") shall be permitted as an optional "modulo" flag when formatting an integer with precision and one of the binary, octal, or hexadecimal presentation types (bases that are powers of two). This first reduces the integer into ``range(base ** precision)`` using the ``%`` operator. The result is a predictable two's complement style formatting with the *exact* number of digits equal to the precision.

This PEP amends the clause of :pep:`3101` which states "[t]he precision is ignored for integer conversions".
