Research direction
No file, test, or entry point is named. Start by locating the analyzer rule or type-checking entry point for arithmetic expressions, then reproduce the two examples from the issue; done means bigint combined with floating-point addition or multiplication receives a warning or error instead of silently producing the shown incorrect results.
Written by the indexing model from the issue text.
Description
Summary of the new feature
When you use bigint and add or multiply a floating point number, the result is wrong.
I discussed it with the PowerShell team but they don't want to fix it.
https://github.com/PowerShell/PowerShell/issues/21341
[double]$r = [bigint]5 * [double]1.5
Write-Host "bigint: $r"
The result is "bigint: 5"
[double]$r = [bigint]5 + [double]1.5
Write-Host "bigint: $r"
The result is "bigint: 6"
