Function malachite_base::num::conversion::string::to_string::digit_to_display_byte_lower

pub const fn digit_to_display_byte_lower(b: u8) -> Option<u8>

Converts a digit to a byte corresponding to a numeric or lowercase alphabetic char that represents the digit.

Digits from 0 to 9 become bytes corresponding to chars from ‘0’ to ‘9’. Digits from 10 to 35 become bytes representing the lowercase chars ‘a’ to ‘z’. Passing a digit greater than 35 gives a None.

Worst-case complexity

Constant time and additional memory.

Examples

use malachite_base::num::conversion::string::to_string::digit_to_display_byte_lower;

assert_eq!(digit_to_display_byte_lower(0), Some(b'0'));
assert_eq!(digit_to_display_byte_lower(9), Some(b'9'));
assert_eq!(digit_to_display_byte_lower(10), Some(b'a'));
assert_eq!(digit_to_display_byte_lower(35), Some(b'z'));
assert_eq!(digit_to_display_byte_lower(100), None);
