    The name was changed to Language Independent Arithmetic (LIA).
Part 1 (ISO 10967-1) covers integer and floating point arithmetic.
It defines two integer division operations, divf (flooring) and
divt (truncating), with corresponding remainder operations for each.
The ISO standard for Modula-2 implemented this by retaining the DIV
and MOD operations (inherited from Pascal) as flooring operations
with their traditional semantics, and introducing / and REM integer
operations with truncating (symmetric) semantics.
