Introduction

digits-to-word is a little npm module written in ES6 to help you spell out numbers in words.

• 99 = ninety-nine
• 99.99 = ninety-nine (umpteen discards anything after the decimal point)
• 108 = one hundred and eight
• 89,828,374,987 = eighty-nine billion, eight hundred and twenty-eight million, three hundred and seventy-four thousand, nine hundred and eighty-seven
• 9,999,999,999,999,999 = nine quadrillion, nine hundred and ninety-nine trillion, nine hundred and ninety-nine billion, nine hundred and ninety-nine million, nine hundred and ninety-nine thousand, nine hundred and ninety-nine

Assumptions

digits-to-word expects string input but will try to deal with number input as well, up to but not including 9007199254740992, which is the biggest number Javascript will nicely turn into a string.

digits-to-word currently handles numbers up to 16 digits long.
