What is the difference between truncating and rounding?

2 Answers. In mathematics, rounding means rounding to the nearest integer, so rounding 3.4 results in 3 and rounding 3.6 results in 4. Truncating , on the other hand, means removing the fractional part altogether, so either 3.4 or 3.6 results in 3. Most programming languages and libraries follow this as well.

Boolean search is a type of search allowing users to combine keywords with operators (or modifiers) such as AND, NOT and OR to further produce more relevant results. For example, a Boolean search could be “hotel” AND “New York”. This would limit the search results to only those documents containing the two keywords.

What symbol keeps search terms in order?
