Entries beginning with numerals are assigned an A Cutter (.A12-.A19) and numbered
to precede all entries beginning with the letter A.

Because of the infinite range of numbers, choose a Cutter toward the center of the
available span when Cuttering for the first number in a class. This will allow room
for both smaller and larger numbers. Follow this practice with relatively low numbers
since decimal fractions are filed in numeric order before the number 1.
