Not realy besides x! = x*(x-1)!. For some things there are approximations but these are only good for small ranges of values and complicated, generaly reserved for factorials of large numbers.
Whole numbers are a proper subset of decimal numbers. All whole numbers are decimal numbers but not all decimal numbers are whole numbers.
Factorials are a mathematics application used for combinations and permutations. The real world application of factorials are used to find the probability of certain things.
For any pair of factorials, a! / a-1! = a. In this instance: 42! / 41! = 42
Any amount of numbers can be in a decimal.
No. Factorials can only be placed on positive whole numbers or 0. For example, 0!, 1!, and 6! are all fine, but 2.5! and (-1)! are not. Since factorials can only be placed on whole numbers, that means you will only be multiplying whole numbers. 100! = 100 * 99 * 98 ... * 1; all those numbers are whole numbers, meaning your answer will be a whole number.
Nothing. Factorials are only defined for whole numbers (non-negative integers).

120. The numbers are factorials: 1, 1x2, 1x2x3, etc.

All real numbers can be represented in the decimal system. Complex numbers can be represented by a pair of numbers in the decimal system.
Decimal numbers that can be expressed as fractions are rational but decimal numbers that can't be expressed as factions are irrational
YES!
