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.

One may also ask, is 3.14 a rational number? Therefore it is a simplified ratio. Since 3.14canbe expressed as 157/50 (that is a rational number),so3.14 is a RATIONAL NUMBER. -2.6 is arationalnumber which can be written-26/10.
