for the error value, we are required to have \(-9999 \leq x, y \leq 9999\), and
the syntax to specify this is two literal numbers divided by an ampersand.
For instance, < span class = "extract" > < span class = "extract-syntax" > 28& -125< / span > < / span > means \((28, -125)\) which is stored as \(-1249972\).
