Features
Spells everything from zero to nine hundred ninety-nine trillion — far beyond what most converters handle.
Writes US dollar amounts the way banks expect: “one thousand two hundred thirty-four dollars and fifty-six cents”.
Rounding is done on the digits themselves, so amounts like $2.675 correctly become sixty-eight cents — never a floating-point surprise.
Plain mode reads decimals digit by digit (“point five six”), and negative numbers get a clean “negative” prefix.
Copy the spelled-out amount straight to your clipboard and drop it into any document or form.
