The writing style
Numbers are written in the American style, without "and": 1,234 becomes "one thousand two hundred thirty-four", 1,250,000 becomes "one million two hundred fifty thousand". British cheques usually include "and" before the last part ("one thousand two hundred and thirty-four") — add it by hand if your bank or style guide expects it. Output is in English only.
