A trillion is an integer. It is also written as 10^12. One trillion is a thousand billion or a million million in most modern English-speaking countries. The number is represented by the prefix “Tera-”.

In British English, the term trillion used to mean “million billion”, “million million million” or 10¹⁸. The difference between the two values is known as the long and short scales of large numbers.
