Returns

• int - The number of bits required (8, 16, 32, 64, or 128).

Raises

• ValueError - If precision is greater than 38 or invalid.

Examples

A number with 38 digits requires 128 bits:

>>> numbers.digits_to_bits(38)
128

A number with 9 digits requires 32 bits:

>>> numbers.digits_to_bits(9)
32
