Constructor
| Name | Signature | Brief |
|---|---|---|
| HugeInt | (val: Any) | Number or text parsing to HugInt |
performs the conversion from text to number assuming hexadecimal representation
Prototype members
| Name | Signature | Brief |
|---|---|---|
| isEmpty | (): Boolean | Return true if zero |
| nonEmpty | (): Boolean | Return true if non-zero |
| size | (): Number | Return number of bits needed to represent |
| toText | (): Text | Return number as hexadecimal text |
| modExp | (exp: HugeInt, mod: HugeInt): HugeInt | Return modular exponentiation |
| toNumber | (): Number | Converts to number (with precision loss) |
| toChunk | (): Chunk | Encodes to binary representation |
Usage notes
When converting from Number type to HugeInt, the limit is 2^53, which is the maximum value that can be safely represented as an integer without precision loss. Attempting to pass a value higher than this limit will raise a ValueError.
Conversely, when converting from HugeInt to Number, values up to 2^1023 - 1 can be converted with some degree of precision loss. Attempting to convert a value higher than this will result in infinity, which can be checked using the isInf method provided by the math library.
the math library also provides the
maxIntvalue, which serves to assess potential precision loss; if a number is less thanmaxInt, its conversion fromHugeIntis considered safe without precision loss
