How to write decimal values in words

Solution 1:

And the numbers afterwards are individual:

One thousand two hundred and ten point eight oh two.

But, as per @Barrie, why? I can think of no case where this would be necessary or appropriate.

Solution 2:

When you are writing the values on a check, say for $193.34, when writing it in words it is customarily done as:

One hundred ninety three and 34/100

Perhaps for your numbers you would use the same convention. For 1210.802, you would write:

One thousand two hundred ten and 802/1000

Solution 3:

Normally, you wouldn’t. In speech, you say the decimal point as ‘point’.
