請問CH32V208在使用log時候報(bào)錯如何處理，已經(jīng)調(diào)用math.h

const? float K=273.15;

const? float? T2=K+25;

const? float B=3950.0;

const? float R25=100.0; //100k熱敏電阻

float Get_Temp(float Rntc)

{

? ? float T1,Temp;

? ? T1=1/((log(Rntc/R25))/B+1/T2);? ? ? ??

//? ? printf("T1=%f\r\n",T1);

? ? Temp=T1-K;

//? ? printf("Temp=%f\r\n",Temp);

? ? return Temp;

}
