🔢 Numeric Literal Notation

🔢 Numeric Literal Notation

📍 Common Suffixes (Intel‑Style)

Suffix	Base / Meaning	Example	Decimal Value	Notes
`h`	Hexadecimal (base‑16)	`4Ah`	74	Add a leading `0` if starting with `A–F` → `0Ah`
`b`	Binary (base‑2)	`1010b`	10	Rare in older docs, common in MASM/NASM
`o` or `q`	Octal (base‑8)	`77o` / `77q`	63	`o` and `q` depend on assembler
(none)	Decimal (base‑10)	`42`	42	Default unless specified

💡 Prefix Alternatives

Prefix	Meaning / Syntax Origin	Example	Decimal Value
`0x`	Hex (C‑style)	`0x4A`	74
`$`	Hex (GAS/AT&T style)	`$4A`	74
`%`	Binary (GAS style)	`%1010`	10

🛠 Assembler Quirks

MASM/TASM: Strict h, b, o usage; needs a leading 0 if the hex value starts with a letter.
NASM/FASM: Accepts both suffix (h) and C‑style (0x) notations.
GAS (GNU Assembler): Prefers $ for constants (AT&T style), no h suffix.
