Convertidor Hex a Decimal

A Hex to Decimal Converter is a mathematical translation utility used to turn Base-16 codes into standard Base-10 integers. This tool is essential for programmers, graphic designers, and memory analysts debugging memory addresses (0xDEADBEEF), interpreting color codes, and reading low-level byte data.

The conversion engine handles the math through a power-of-16 pipeline:

1. Input Parsing: The tool accepts identifying prefixes (0x, #) and strips them.
2. Digit Mapping: It translates letters to numbers:
   • 0-9 -> 0-9
   • A -> 10, B -> 11, C -> 12, D -> 13, E -> 14, F -> 15.
3. Summation: It calculates the value based on position ($16^n$).
   • 1F
   • $1 \times 16^1 = 16$
   • $15 \times 16^0 = 15$
   • Total: 31.
4. Verification: It converts back to binary to ensure the Bit Pattern is preserved.

The History of Hex: The 4-Bit Miracle

Why 16? Because $2^4 = 16$.

• Nibbles (1960s): A "Nibble" is 4 bits (half a byte). Hexadecimal perfectly represents one nibble per character. A full byte (8 bits) is exactly two hex characters (FF).
• The Color Revolution (1990s): HTML defined colors using 3 bytes (Red, Green, Blue). Hex became the standard because #RRGGBB is easy to write.
• The Debugger: Hex allows a programmer to view a 1GB memory dump on a single screen. Reading that in binary would take Current Year + 10.

Technical Comparison: Reading Data

Understanding the density of information.

Value (Decimal)	Binary (8 chars)	Hex (2 chars)
0	00000000	00
10	00001010	0A
255	11111111	FF
1024	000001000...	400

Security and Privacy Considerations

Your calculation is performed in a secure, local environment:

• Local Logical Execution: All math is performed locally in your browser. Your private data never touches our servers.
• Zero Log Policy: We do not store or track your inputs. Your Memory Offsets and Private Keys remain entirely confidential.
• W3C Security Compliance: The tool operates within the standard browser sandbox, ensuring no interaction with your local file system or Private Metadata.
• Privacy First: To maintain absolute Data Privacy, the tool functions as an anonymous utility.

How It's Tested

We provide a high-fidelity engine that is verified against Standard Math Libraries.

1. The "Max Byte" Pass:
   • Action: Input FF.
   • Expected: Result is 255.
2. The "Prefix" Check:
   • Action: Input 0xFF or #FF.
   • Expected: The tool strips the prefix and returns 255.
3. The "Overflow" Verification:
   • Action: Input a 64-bit Hex string.
   • Expected: Uses BigInt logic to return the correct massive number without scientific notation errors.
4. The "Invalid" Defense:
   • Action: Input 12G.
   • Expected: Flags "Invalid Hex Character (G)."
