% Warning: floating point invalid operation

[Andrea Mecchina]

Hi everybody. I constantly get this warning when i try to compile a procedure and I can't figure out what's the problem. Even if the procedure is void I get the error. What could be the problem? Andrea Mecchina

Without knowing the details I can't say anything. I need FL version, operating system, sample code.

I'm using the latest version, 0.79.45, on Mac OS X 10.14.1. For example, if to compile a simple text file with: PRO hello_world PRINT, "Hello World" END I get the program compiled but I get the warning. If I launch it I get the same warning (even if the program works). Another example: if from the bar FL> I digit "x=3.0" I got nothing but if then "print,x" I get the number but then the warning. I can't figure out what's appening.

Thank you for your work and your help, Andrea

If I give the command " print,'Hello' " I sometimes get the warning and other times not, I really can't figure out

OK. I could reproduce it on MacOS 10.14.1: the message appears even after an empty input line (single return key). It appears only in the graphical interface, command line is OK. Also, FL was built on OSX 10.6.8, where everything works fine. It is probably some incompatibilty between 10.6 and 10.14. I'll clear the math flags for MacOS after reading the input in the next snapshot, hopefully before Xmas.

Your work it's very precious for other students in my same class. We look up for this update, thank you very much.

I think there might be something that doesn’t work correctly even in the terminal version, cause sometimes I get error compiling the simple procedure:

PRO ImageArray WINDOW, 0, XSIZE=256, YSIZE=256 END

I always get errors when I execute it. I get the error in the first compiling even with a void procedure. Thank you for your support, very appreciated, Andrea Mecchina
