floating point error

junesikkim — Mon, 11 May 2015 12:13:28 GMT

i'm using codewarrior ver 10.6 and MCU5606B dev board for intelligent car

i need to use floating point because i'll use IMU sensor & PID controll

so I add "include <float.h>" , plus arithmetic operation(a=a+5; , declare float a) and lib path but error occured like below

please advise how can i solve this problem?

Is the runtime library added into the project? Please see the screenshot in below for the necessary libraries for a Qorivva project.

I also attached a simple project in my test, it builds well in CW10.6.

If this does not help, please attach a simple project to help us reproduce the error. Thanks!

Thank you for your advice. But but that method isn't solution to me.

That method is using code warrior project. My project was made via RAppid.

Please let me know about the floating point calculation using RAppid.

Please answer. Thank you~
