What happened?
If a prompt contains a fractional number, the whole rendering process produces a black image. Integer numbers cause no problems. If having a fractional number in the prompt is a syntax error, it should be caught before generation - think of poor souls who generate 30 minutes per picture only to find out they accidentally got a number into the prompt.

isnt that because Invokeai is trying to parse the prompt for certain ast-format? such as: (subject:1.1)
The problem is in the way numeric attention values are parsed in the prompt: 2.0 is interpreted as 2 with a weight of .0, which is most likely a bug.
This happens similarly for any words in the prompt that end with a decimal point (.) followed by some digits, such as f/2.8, which is parsed as f/2 with a weight of .8.
Intentional use of numeric attention values following words are parsed incorrectly as well. The prompt intricate1.5 is parsed as intricate1 with a weight of .5.
My suggestion would be to change the prompt syntax specification to only allow numeric weights after parentheses to avoid these issues.
