Behavior

 * Non-integers and values less than zero are given in numerals (e.g. 0.5, -3).
 * Integers from zero to nine are spelled out in words (e.g. five).
 * For integers greater than or equal to ten:
 * By default, numbers expressible in one or two words are spelled out (e.g. fifty-six), and numbers requiring three or more words are given as numerals (e.g. 310).
 * If the argument "forcenum" is given with a value of "true" (or equivalent per Template:Yesno), integers greater than or equal to ten are always expressed as a numeral.
 * Numbers greater than one million are rounded to at most two significant figures when expressed with words.
