TMS320F28P650DH: fminf/fmaxf functions in CLA

Part Number: TMS320F28P650DH

Tool/software:

Hi Experts,

I am asking it for my customer. 

In the CLA, using the fminf/fmaxf functions triggers warnings but does not cause errors, and the functionality appears to work normally:

 "E:/workspace/git/1-215/dsp/KL_PCS_F28P65x_cpu1/src/module/control/INV/MBD/PWM_Gen/PWM_Gen.h", line 358: warning #225-D: function "fminf" declared implicitly "E:/workspace/git/1-215/dsp/KL_PCS_F28P65x_cpu1/src/module/control/INV/MBD/PWM_Gen/PWM_Gen.h", line 721: warning #225-D: function "fmaxf" declared implicitly

I tried adding preprocessor directives, as shown in Figure 1, but the warnings persist.

The compiler configuration is shown in Figure 2.

How can these warnings be resolved? Additionally, I am concerned that these warnings might cause issues under certain circumstances. I would appreciate an official explanation. Thank you!

Best Regards,

Dean
