In programming, what is the primary characteristic of integer division?
In programming, what is the primary characteristic of integer division?
- It returns the exact quotient, including the decimal part.
- It raises an error if the divisor is zero.
- It automatically rounds the result to the nearest whole number.

Study Notes
- Explicit conversion is a type of conversion where the programmer manually changes a data type to another, often using a specific function or syntax.
- A floating-point number can have a fractional part represented with decimal points.
- Integer division is a division operation where the result is the whole number part of the quotient, discarding any remainder.
- Implicit conversion is a type of conversion where the programming language automatically changes one data type to another without the programmer's intervention.
- Type conversion (type casting) is the process of changing a value from one data type to another, which can be done explicitly by the programmer or implicitly by the programming language.
- An end-structure statement marks the end of a block of code, such as the end of a loop or an if statement.
- A block is a group of statements that are executed together, typically enclosed in curly braces or defined by indentation.
- A dual-alternative if statement provides two paths: one for when the condition is true and another for when it is false; also known as if-else.
- A loop structure is a way to repeat a block of code multiple times based on a condition, such as for loops or while loops.
- Loop body: the set of statements inside a loop that are executed each time the loop runs.
