So far it is a googol. A googol is a number with a hundred zeroes or: 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
A googolplex which has a googol zeros (a googol has 100 zeros after it) is a big one, but there is no "highest number", because you can always add one to it. Some people believe infinity is the highest number, but you can always just add one.
Infinity is the highest number of all. Technically, some people say that infinity is too much that infinity is 0.
Infinity is a concept, not a number. Even if it were considered such, infinity plus one is also infinity, and so infinity minus one is still infinity.
There is no largest number under infinity because what ever the highest number is, one can always be added to it, making the new number the highest number.

There is no answer for this, there is an infinity possibilities.
Infinity is not a number; it is a concept. There is no highest number, because you can always add 1 to it and create a higher number. If this new number is the highest number, then add 1 again and it isn't. The process can never end, so infinity is used to describe the idea: a process that never ends.
Infinity is an imaginary number so if you meant the previous whole number to infinity it would be expressed as infinity minus one. If you meant the highest number possible before reaching infinity is would be: infinity - 1/infinity
The highest single number in the decimal system is 9. The highest single number would vary depending on what base you are using, for instance the highest single number in the binary system is 1. The is no 'highest' number. There is a concecept call infinity but that is not really a number but a mathematical tool. There is no such thing. Anything number that you can think of you can always add one more to it. Some people might say infinity is the highest single number, but infinity is a concept not a number.
