Siemens Step7 Real Value Displayed as Hex?

[hcl3646]

Hi,

I'm writing a program to perform some basic math calculations, but somewhere in the middle something's going wrong, and variables with a real datatype are displaying hex values, specifically 16#7FC0_0000.

Is this a known code (like NaN)? Has anyone ever experienced this before? Any info/advice would be appreciated.

You get this as result from a division by zero.
