What is 23 in decimal?

Answer 1

If this number is exactly 23 then it is a whole number. It can be written as 23.0 or 23.00 or any number of zeros following the decimal. Numbers are sometimes written like this to expess its preciseness, especially in scientific expiriments. i.e (41.000 to differentiate it from 41.001). You sound like kid who just want a simple answer for his homework though, so i say go with 23.0.
