Directed Number

Directed Number
Numbers that can be negative as well as positive.

There is size (such as 3 or 9.9) and direction (− or +)

Positive numbers often leave off the "+" sign, so "+5" is written "5"

Examples of Directed Numbers:
−15.1 (negative fifteen point one)
−3 (negative three)
2.22 (positive two point two two)
12 (positive twelve)

(Note: when it is a whole number it is also an integer, as integers are whole numbers that can be negative or positive)
