An integer parameter will default to decimal and may be prefixed with
-a `-` for negative numbers. Alternativly, a hexidecimal number may be
+a `-` for negative numbers. Alternatively, a hexadecimal number may be
used by prefixing the number with `0x`, or an octal number may be used
if a leading `0` is present.

usage entirely.
