fromTwosComplement

The fromTwosComplement function takes a hexadecimal string value and converts it into a decimal number or big integer. The function is a part of the web3-utils library and is designed to be used with the Ethereum blockchain.

The function takes an optional parameter nibbleWidth which specifies the nibble width of the hex string. The default value for nibbleWidth is 64.

The fromTwosComplement function is useful for converting twos complement values, which are commonly used in cryptography and computer science, into decimal numbers or big integers. The function can handle both positive and negative values, and will return a big integer if the value exceeds the range of a 32-bit integer.

Here are some examples of how the fromTwosComplement function can be used:

In the first example, the function takes a 32-bit twos complement value and returns a decimal number. In the second example, the function takes a 32-bit twos complement value and returns a big integer.
