digits

digits([T], n, [base], [pad])

Returns an array with element type T (default Int) of the digits of n in the given base, optionally padded with zeros to a specified size. More significant digits are at higher indexes, such that n == sum([digits[k]*base^(k-1) for k=1:length(digits)]).

Examples

1. Get the digits of an integer:

   julia> digits(1234)
   4-element Array{Int64,1}:
   4
   3
   2
   1

   This example returns an array of the individual digits of the integer 1234.

2. Specify the base of the number:

   julia> digits(1234, base=2)
   11-element Array{Int64,1}:
   0
   1
   0
   0
   1
   1
   0
   1
   0
   0
   0

   Here, the binary representation of the number 1234 is obtained by setting the base argument to 2.

3. Pad the result with zeros to a specific size:

   julia> digits(1234, pad=8)
   8-element Array{Int64,1}:
   0
   0
   0
   1
   2
   3
   4
   0

   The pad argument is used to specify the desired size of the result. In this case, the result is padded with zeros to a length of 8.

4. Specify the output element type:

   julia> digits(Float32, 1234)
   4-element Array{Float32,1}:
   4.0
   3.0
   2.0
   1.0

   By providing Float32 as the first argument, the resulting array will have the element type Float32.

Common mistake example:

julia> digits(1234, base=1)
ERROR: ArgumentError: base must be >= 2

In this example, an error is thrown because the base provided is less than 2. The base argument must be a positive integer greater than or equal to 2.
