[llvm] [LangRef] Fix examples for float to int saturating intrinsics (PR #115629)

[via llvm-commits]

https://github.com/williamfedele created https://github.com/llvm/llvm-project/pull/115629

See #113529 for raised issue.

As per the [LangRef:Simple Constants](https://llvm.org/docs/LangRef.html#simple-constants), exact decimal values of floating-point constants are required. For instance, 23.9 is a repeating decimal in binary and results in the reported error.
