@webassemblyjs/helper-numbers
Advanced tools
The @webassemblyjs/helper-numbers package provides utilities for handling numbers in WebAssembly modules. It includes functions for parsing and formatting numbers according to the WebAssembly specification. This can be particularly useful when working with WebAssembly binary files or generating WebAssembly code programmatically.
Parsing floating point numbers
This feature allows for the parsing of floating point numbers from their string representation into their binary format as used in WebAssembly. The code sample demonstrates parsing 32-bit and 64-bit floating point numbers.
"use strict";\nconst { parseF32, parseF64 } = require('@webassemblyjs/helper-numbers');\nconsole.log(parseF32('0x1.fffffep+127'));\nconsole.log(parseF64('0x1.fffffffffffffp+1023'));Formatting floating point numbers
This feature enables the formatting of floating point numbers from their binary representation in WebAssembly to a human-readable string format. The code sample shows how to format 32-bit and 64-bit floating point numbers.
"use strict";\nconst { formatF32, formatF64 } = require('@webassemblyjs/helper-numbers');\nconsole.log(formatF32(1.5));\nconsole.log(formatF64(-1.5));Parsing integer numbers
This functionality allows for the parsing of integer numbers from their string representation into their binary format as used in WebAssembly. The code sample demonstrates parsing 32-bit and 64-bit integer numbers.
"use strict";\nconst { parseI32, parseI64 } = require('@webassemblyjs/helper-numbers');\nconsole.log(parseI32('0xff'));\nconsole.log(parseI64('0xff'));The 'long' package provides comprehensive support for 64-bit integers, including both signed and unsigned types. While it focuses on 64-bit integer arithmetic and comparison operations, it does not specifically cater to the WebAssembly number formats or parsing from specific encodings, making it less specialized for WebAssembly use cases compared to @webassemblyjs/helper-numbers.
bignumber.js is a library for arbitrary-precision decimal and non-decimal arithmetic. Unlike @webassemblyjs/helper-numbers, which is tailored for WebAssembly's number formats, bignumber.js offers a broader range of arithmetic operations and supports arbitrary precision, making it suitable for financial and other precision-critical applications.
