English decimal point vs comma. Putting a decimal point instead of a comma can make thousands of dollars of difference. So, let’s make sure we get it right.

COMMAS
- Just like in money, we write and say large whole numbers in the same way.
- a comma will always indicate a separation between hundreds, thousands, millions, and so on.
- 10,001 – ten thousand and one
- They sent us an extra piece, so now we have ten thousand and one pieces all together.
- There are over 3,000 (three thousand) people attending the event this weekend.
DECIMAL POINT
- Anything left of the decimal point is considered to be the whole number.
- Anything right of the decimal point is called the fractional number
- This number can be pronounced as:
- three hundred twenty-one point four five.
- Three hundred twenty-one and forty-five hundredths

ZERO
- When using a decimal point, the fractional number zero will be pronounced as ‘oh’.
- The decimal point will be pronounced as ‘point’.
- 32.06 – thirty-six point oh six
- 4.305 – four point three oh five
COMMON MISTAKES
- In Spanish and many other European languages, the comma and the decimal point are in the opposite positions which causes many problems.
