The part of the error that says "no implicit conversion of nil into String" suggests that you should look at the part of the code that is converting something to a string: item['quantity'].to_s A quick web search of 'ruby nil' says that it means nothing is there or, in this case...
With arg: Optional[float] the argument is typed as a Python float (or None) and so Cython does an exact type-check for the Python object. Right now we don't do much with the knowledge that it's a Python float, but in principle any optimizations would be based on that exact type ch...

During our last session in SQL Data Saturday, we received a question about if it is possible to know all the conversion implicit captured by Query Data Store. In the following example, I would like to share with you an example how to capture this considering a...

This section describes type casting supported in Java: up casting (widening reference conversion) and down casting (narrowing reference conversion). Cast operation can be written explicitly with the cast operator (T), or implicitly with no operator.
"Error 1 The type 'TEST.SomeStuffs' cannot be used as type parameter 'T' in the generic type or method 'Grasshopper.Kernel.GH_Param<T>'. There is no implicit reference conversion from 'TEST.SomeStuffs' to 'Grasshopper.Kernel.Types.IGH_Goo'. C:\...\SomeStuffs.cs" ...

I believe this error message can be tracked all the way to the implicit tensor type conversion. Expected behaviour It would seem that it would save a few people hours of debugging time if the TypeError was worded, in this specific case, differently: TypeError: cannot convert an object of ...
The "implicit conversion from 'number' to 'string'" is brought about in mql4 when you convert a number variable to a string variable in your code without explicitly coding it to do that. For example: int number = 10; Alert(number); ...
