Double a number with or without decimal places.


Double a number with or without decimal places. (Example for this math problem)


This exercise is about doubling numbers. In particular, the concept of doubling as multiplication by two is the main focus here. Therefore, the problem definition is deliberately kept short. The request "double" stands for itself and the meaning for the arithmetic task, which follows from it, must be developed. Both whole numbers and decimal fractions, i.e. numbers with digits after the decimal point, can be given for doubling.

The numbers can lie in a selectable number range, in which the outcome will also fall. The number of decimal places is adjustable.

The number of numbers to be doubled in this task can also be set.
