ERROR: floating constant is out of range

4 views (last 30 days)
I have created a algorithm in Simulink. I tried to implement this model to TI TMS320F28379D LAUNCHXL board embedded target. When I try to build the model, I receive the following error messages.
This is one of the code segments that caused error

I wonder where that constant comes from; too bad it isn't documented. It happens to be 0x1cc0000000000000 but that does not tell me anything about what it represents.
Ah... with further checking I see that it is
format long g
ans =
and that suggests its replacement value should be
ans = single

That number is well within the range of IEEE double precision floating point numbers, but the TI TMS320F28379D has native 32bit IEEE single precision floating point. I'm not sure what the C compiler for it does with double precision data, but based on what you have shown, it doesn't seem to support IEEE double precision floating point, even in emulation. Try using single precision.

The easiest way to accomplish this with simulink is to use the Single Point Converter in the Apps tab
