Hello,

with the ST10F269 are there any known errors, when there is a multiplication

with 0 using floating-point variables?

Best regards

Patrick

Hello,

I'm using the TASKING tools for C166/ST10 v7.5 r6

Hello,

Multiplying by zero does not cause any error with the ST10F269.

Please take a look at the C Compiler manual, ''Floating point trapping'' and ''Handling Floating point traps in a C application'' sections. So probably something else is going wrong. Please take a look at the value of the trap code (register R1) to find out what caused the error (exception). To do so, set a breakpoint on label __FPTRAPLOOP.

Regards,
