Function hexDecValueToNumber

Converts a string or number representing a numeric value into a number.

• If the input is already a number, it is returned as is.
• If the input is a string starting with #x, it is parsed as a hexadecimal number.
• Otherwise, the string is parsed using Number(), which supports decimal, hexadecimal (0x), binary (0b), octal (0o), and floating-point literals.

Returns

The numeric value parsed from the input. If parsing fails, returns NaN.

Example

hexDecValueToNumber(42);           // returns 42
hexDecValueToNumber("#x2A");       // returns 42 (hexadecimal 2A)
hexDecValueToNumber("42");         // returns 42 (decimal)
hexDecValueToNumber("0x2A");       // returns 42 (hexadecimal)
hexDecValueToNumber("0b101010");   // returns 42 (binary)
hexDecValueToNumber("0o52");       // returns 42 (octal)
