Function encode_num 

pub fn encode_num(num: f64) -> String

Encode a regular number to compressed string with ‘n|’ prefix.

This function is for regular (finite) numbers only. Special values (Infinity, -Infinity, NaN) are handled separately in memory.rs based on configuration settings.

Arguments

• num - The f64 number to encode (should be finite)

Returns

String in format "n|<number>"

Example

assert_eq!(encode_num(42.5), "n|42.5");
assert_eq!(encode_num(-3.14), "n|-3.14");
assert_eq!(encode_num(0.0), "n|0");

Note

For special values (Infinity, NaN), the handling depends on config:

• preserve_nan/preserve_infinite: encoded as N|0, N|+, N|-
• Otherwise: converted to null (empty string)
