to-base()

This is a quick one. Just some code to convert from base 10 to a base of your choice.
First the python:

# convert decimal number to base b.
# number, base need to be kets. category_number_to_number() should take care of that.
def decimal_to_base(number,base):
  r = int(category_number_to_number(number).value)
  b = int(category_number_to_number(base).value)
#  print("r:",r)
#  print("b:",b)
  current_base = 1
  result = superposition()
  while r > 0:
    rem = r%b
    r //= b
    result += ket(str(current_base),rem)
    current_base *= b
  return result  

Now a couple of examples:

sa: to-base(|255>,|2>)
|1> + |2> + |4> + |8> + |16> + |32> + |64> + |128> 

sa: to-base(|213>,|2>)
|1> + 0.000|2> + |4> + 0.000|8> + |16> + 0.000|32> + |64> + |128>

sa: to-base(|359822>,|10>)
2.000|1> + 2.000|10> + 8.000|100> + 9.000|1000> + 5.000|10000> + 3.000|100000>

Probably don't need any more examples than that, the idea is simple enough!

Update: now with the magic of tables:

sa: table[base,coeff] to-base(|255>,|2>)
+------+-------+
| base | coeff |
+------+-------+
| 1    | 1     |
| 2    | 1     |
| 4    | 1     |
| 8    | 1     |
| 16   | 1     |
| 32   | 1     |
| 64   | 1     |
| 128  | 1     |
+------+-------+

sa: table[base,coeff] to-base(|213>,|2>)
+------+-------+
| base | coeff |
+------+-------+
| 1    | 1     |
| 2    | 0     |

| 8    | 0     |
| 16   | 1     |
| 32   | 0     |

sa: table[base,coeff] to-base(|359822007>,|10>)
+-----------+-------+
| base      | coeff |
+-----------+-------+
| 1         | 7     |
| 10        | 0     |
| 100       | 0     |
| 1000      | 2     |
| 10000     | 2     |
| 100000    | 8     |
| 1000000   | 9     |
| 10000000  | 5     |
| 100000000 | 3     |

Nice.

Update: now with the magic of "to-comma-number":

sa: table[base,coeff] to-comma-number to-base(|10973498714>,|2>)
+---------------+-------+
