I have been using the Azure resource estimator to evaluate the resource requirements for algorithms like Shor's and HHL. However, I encounter an error ("Value too large") when entering larger real-world inputs, such as increasing the bit-length for Shor or the matrix size for the HHL. Is this error indicative of limitations within the tool, or are there potential fixes? I have also attempted the implementation of Shor's algorithm from the tutorial: https://learn.microsoft.com/en-us/training/modules/estimate-resources-quantum-algorithms/5-estimate-resources-with-azure-quantum, but it fails for integer bit-lengths greater than 31.

What specific inputs or problem sizes were you trying when the "Value too large" error appeared?
Which version of the Azure Quantum Resource Estimator or QDK were you using?
Are you using the standalone estimator SDK or running the estimation via the Azure Portal or CLI?

2025-07-03T19:11:36.4866667+00:00 The resource estimator raised the "Value too large" error when trying to input bit sizes greater than 31 to the implementation given in the tutorial for Shor's algorithm. I have been using the QDK extension (version 1.18.0) to estimate the resources in VS Code.
