Questions about Number to words converter

What happens to decimals when no currency is chosen?

They are read digit by digit after the word point, exactly as typed, so 12.5 becomes twelve point five and 3.05 becomes three point zero five. A value such as 0.5 reads as zero point five.

How are sub-units named for each currency?

Dollars, euros and rupees take cent, cent and paisa, with the plurals cents, cents and paise. The British pound uses penny and pence, so 2.50 reads as two pounds and fifty pence and 1.01 as one pound and one penny.

How does it decide between one dollar and two dollars?

Each part is counted on its own. The main unit is singular only when its count is exactly one, so 1.01 in dollars reads as one dollar and one cent, and 2.01 reads as two dollars and one cent.

What is the largest number it accepts?

The whole part may have up to 36 digits, which reaches into the decillions, and every digit is kept exactly. Anything longer is refused with a message. Exponent notation such as 1e5 is not accepted.

Does it write hyphens or the word and?

Neither. Twenty-one is written twenty one, and there is no and after hundred, in the American style. The word and appears only before a currency's sub-unit.

How are negative numbers and zero shown?

A minus sign becomes the word negative at the front, and zero is written as zero, followed by the plural currency name when one is selected. Minus zero is just zero.
