convert string value to float or int

I had created a string with float values separated by ; (semicolons)
I split on ; and tried to convert to float, but this didn´t work, even when to_u32, to_u64 and to_f64 nodes exist.

Start by reproducing the semicolon-separated string case described in the issue and inspect how split string values are passed to the to_u32, to_u64, and to_f64 nodes. Identify the conversion path responsible for rejecting or mishandling the values, then verify that valid split numeric strings convert successfully to integer and float outputs.
