# Class BSV::Script::ScriptNumber **Inherits:** `Object` **Includes:** `Comparable` Bitcoin script number: arbitrary-precision integer with sign-magnitude little-endian byte encoding. Script numbers use a specialised encoding where the sign bit occupies the MSB of the last byte, and the magnitude is stored little-endian. This class handles encoding/decoding, minimal encoding validation, and arithmetic operations as required by the script interpreter. ## Constants ### `INT32_MAX` Maximum 32-bit signed integer value. ### `INT32_MIN` Minimum 32-bit signed integer value. ### `MAX_BYTE_LENGTH` Maximum byte length for script numbers (post-Genesis: 750 KB). ## Attributes ### `value` [R] - **@return** [Integer] the numeric value ## Public Class Methods ### `from_bytes(bytes, max_length: = MAX_BYTE_LENGTH, require_minimal: = false)` Decode little-endian sign-magnitude bytes into a ScriptNumber. Encoding: little-endian magnitude with sign bit in the MSB of the last byte. 127 -> [0x7f] -127 -> [0xff] 128 -> [0x80 0x00] -128 -> [0x80 0x80] 256 -> [0x00 0x01] -256 -> [0x00 0x81] ### `minimally_encode(data)` Strip trailing zero-padding while preserving sign. ## Public Instance Methods ### `%(other)` Remainder with sign of dividend (matching Bitcoin consensus). - **@raise** [ScriptError] ### `*(other)` Not documented. ### `+(other)` --- Arithmetic (returns new ScriptNumber) --- ### `-(other)` Not documented. ### `-@()` Not documented. ### `/(other)` Truncated-toward-zero division (matching Bitcoin consensus). - **@raise** [ScriptError] ### `<=>(other)` Not documented. ### `abs()` Not documented. ### `initialize(value)` - **@return** [ScriptNumber] a new instance of ScriptNumber ### `to_bytes()` Encode as little-endian sign-magnitude bytes. ### `to_i()` Not documented. ### `to_i32()` Clamp to int32 range (for opcodes that need bounded indices). ### `zero?()` - **@return** [Boolean]
