a "flat" number

Not in AmE. We might call those "round" numbers.

I don't understand 'flat' used in this way.

Do you mean a whole number? (no decimal places)

Or an even number? (2,4,6,8,10 etc)

Or a round number? (hard concept to describe...it means no fiddly little digits involved - so we might round 43 to 40 for example, or 1896 to 1800. To go to the nearest number ending in 0).

I think in reality, there isn't a single commonly used term to describe these numbers..

In additional to just saying something is a round number, we can use 'rounded to the nearest ...' to give a little more detail. For example, the number 3,031 could be 'rounded to the nearest thousand', to give 3,000. You could also refer to this as an 'approximation'.

00the the word integer use in programing language. which represent the round numbers. such as 100,567,789 0-

It's used in the expression "A flat zero", so only when talking about the number zero as an emphasis.

I think it could be an alternative name for "whole" numbers.
