ttnn.ldexp_bw operation fails with low PCC (eg 0.98)

Steps to reproduce

You can reproduce this error with sweep test tests/sweep_framework/sweeps/eltwise/unary_backward/ldexp_bw.py. To run:

python3 tests/sweep_framework/runner.py --elastic cloud --module-name eltwise.unary_backward.ldexp_bw

Results can be found on elastic cloud as explained here: https://github.com/tenstorrent/tt-metal/tree/main/tests/sweep_framework

@nemanjagrujic Do we need to checkout to specific branch to get the test file that mentioned in the description? I didn't find that in main

[nemanjagrujic]

@umadevimcw Checkout ngrujic/sweep-tests-1. I hope I will merge it soon.

The problem is the range of input passed to the above op, ldexp depends on exp op. In the exp op, there is condition available to check whether input is > 89 and < -42. Please find the below image

In the below you can find a simple python code where if the exp(89) is very large number and exp(-42) is too small number hence ttnn exp has such condition. Hence I have updated the range in the test and submitted the PR #14996
