Ethereum: Incorrect parsing
eters’ U256 string the problem .JS
When Ekarram’s Jason’s RPC API is a general task, parsing 256-bit integers (U2566). Howver, there aressulis that cause the method use in it example.
Problem: U256 Thread Analysis
In the ES, Jjs, JJs, tostt () from stt (3)string ()string is 26-biters likes likes 26-biters. The problem lies thee the petroscers handle:
Rust
DER_IN = U256 :: From ("10000000000"). Unwrap ();
What’s going on herre:
U256 :: Trying to parse ass as astring hexadecate number.
- Howver, the Ehers.Jase assumes that input data is unlocked. Parcers tri to interpret the entire that walue as a double walue.
- As a result,
DES_in$1000000000 (10000000000), a not signed up 256-bit.
** result: U256 incorrectly parsing
After calling an analysis (), an error message indiciates that analysis.
Javascript
ERROR: Invalid argument type U256 :: From U256 :::::
To resolve that problem, the EEHERS.
Correcting the problem
If one is solution is to use the ideas () method alllowing us to specify the input format:
Rust
DER_IN = U256 :: Wears ("1000000000", & [0x10] U8)
.unwrap ();
The printing press! ("Analyzed Amount: {}", defst_in);
This corrected code:
- We q256 :: apple (d) We parse 256-bit integer.
- Input data is a messy this suits the model (`100000000), that mervads.
conclusion
Avoid mistakes U256 string in Eters.js .JS , be it to the the itic () method. This guarantees that the input data is correctly interpreted as a 256-bit integer (32 bys long) as a 256-biter.
Following this correted code example, you will analyzed the 25 chours of unmerge in Eetihar Associates.
