/**
 * Flexible function to convert various inputs to numbers whenever possible
 *
 * @param value - Value to convert (any type)
 * @returns Converted number, or NaN if conversion is not possible
 *
 * @description
 * This function has the following features:
 * 1. Converts null, undefined, and empty string to 0
 * 2. Returns numbers as-is if already a number type
 * 3. Properly handles infinity (Infinity, -Infinity)
 * 4. Supports string representations of hexadecimal (0x), octal (0o), and binary (0b)
 * 5. Properly parses floating-point number strings
 * 6. Extracts numbers from strings that start with numbers when possible
 * 7. Returns NaN if none of the above conditions are met
 *
 * @example
 * flexibleNumberConversion(123)        // 123
 * flexibleNumberConversion("456")      // 456
 * flexibleNumberConversion("78.9")     // 78.9
 * flexibleNumberConversion("3.14e2")   // 314
 * flexibleNumberConversion("0xFF")     // 255
 * flexibleNumberConversion("42px")     // 42
 * flexibleNumberConversion("")         // 0
 * flexibleNumberConversion("not a number") // NaN
