Program Plan Intro

Integer division:

When both operands are integer data types, the resultant statement will be in integer division which means the outcome of the division will also be an integer data type. If there is a remainder, it must be ignored.

Example:

The example for the integer division is as follows:

double value;

value = 5 / 3;

In the above example, the outcome of the “5” by “3” is stored in the variable “value”. The value “1” is stored in the variable “value” because both “5” and “3” are integers, so the decimal part of the result must be truncated.

Floating-point division:

When both operands are floating-point or any one of the operand is a floating-point, the resultant statement will be in floating-point division, which means the outcome of the division will be a floating-point data type.

Example:

The example for the floating-point division is as follows:

double value;

value = 5.0 / 3;

In the above example, the result of the “5.0” by “3” is stored in the variable “value”. The value “1.6667” is stored in the variable “value”, because “5.0” is the floating-point data type and “3” is an integer data type, so the result has a floating-point value.
