Bug: Numeric Conversion Errors in Statistical Functions
The f64 to u64 conversions in fn_poisson_dist, fn_binom_dist, and fn_binom_dist_range can panic. This occurs for negative input values (including NaN or negative infinity, due to premature casting before validation) or for excessively large positive values exceeding u64::MAX. This leads to a crash instead of returning a NUM error.
