Question:
Why does the STING_TO_INT block has a different behavior when the string on the input has letters in it. Quantum will convert letters to numbers, but the M580 will just ignore the letters.
Answer:
Engineering told us that the way the M580 handles the block is the way it was always supposed to be handled, meaning that only digit should be presented to the input string of the block.
The reason they are saying this is because if you look at system %S18
Having a character that is not a number will trigger an arithmetic error as can be seen below in the M580
- With only number, no error
- With a letter, it triggers the error
Let's check with a Quantum CPU
So we see that the Quantum also reports an arithmetic error, even if it does some type of conversion.
Basically engineering says that the block is "fixed" and behaves correctly on the M580 and that it never did on the Quantum.
