/**
 * Gets the number in abbreviated form in a locale-sensitive manner. This function
 * scales the number down to the smallest it can be, taking only up to 4 significant
 * digits, and rounding the rest. ie. 12345678 becomes "12M" in English.
 *
 * The abbreviation words/letters can have the length "short" or "long", specified
 * with the "length" property in the options. If "short",
 * then this function uses an abbreviation of the bucket such as "12M". If "long",
 * then the name of the bucket is written out in full, such as "12 million".
 *
 * For locales that have complex plurals, such as Russian or Polish, this function
 * returns the correctly pluralized suffix/prefix to go along with the scaled number.
