Function get_binary_width_from_digits 

pub fn get_binary_width_from_digits(digits: u16) -> u16

Map a COBOL PIC digit count to the corresponding USAGE BINARY storage width in bits (NORMATIVE).

Follows the COBOL standard mapping:

• 1-4 digits -> 16 bits (2 bytes, halfword)
• 5-9 digits -> 32 bits (4 bytes, fullword)
• 10-18 digits -> 64 bits (8 bytes, doubleword)

Arguments

• digits - Number of digit positions declared in the PIC clause

Returns

The storage width in bits: 16, 32, or 64.
