**number**pi, denoted π, is awell-knownirrational

**number**that is generally known to havevalue

**3.14**. However,

**3.14**is actually the

**number**π rounded to two decimal places, and is not thetrue value ofπ. Therefore, there is often some confusion as towhether

**3.14**is a rational or anirrational

**number**.

Also to know is, can pi be a real number?

**Pi** is an irrational **number**, whichmeansthat it is a **real number** that cannot be expressed byasimple fraction. That's because **pi** is whatmathematicianscall an "infinite decimal" — after the decimalpoint, thedigits go on forever and ever.

**3.14**canbe expressed as 157/50 (that is a

**rational number**),so

**3.14**is a

**RATIONAL NUMBER**. -2.6 is a

**rationalnumber**which can be written-26/10.

Likewise, people ask, what classifies as a real number?

**Real Number**A **real number** is a**number**that can be plotted on a **number** line. **Realnumbers**include all rational and irrational **numbers**.Whole**Numbers**The whole **numbers** are all positivecounting**numbers** and zero. The whole **numbers** are 0,1, 2,3,

A **real number** is a **number** that canbeexpressed in decimal form. Everything else is **not arealnumber**. Colors, sounds, plants, √red ,and.15+×26.78.24.36 are **not real numbers**. Within therealmof **numbers**: even roots of negative **numbers**(square,4th, 6th, etc roots of negative **numbers**) are **notrealnumbers**.
