math calculation doens not worked in mikroc pic

[mokashiswapnil]

Hi ,this is my mikroc code.I am not getting temp value on lcd .
float y,rtdr,temp;
char opr[30];
y = 0.15274- (rtdr-100.0)*2310.0e-7;
if(y>= 0)
y= sqrt;
temp = (y-0.39083)/(-0.0001155) ;

FloatToStr(temp,opr);
Lcd_Out(1,1,lcd);


i am not getting value of y also value of temp.

float y,rtdr,temp;
char opr[30];
y = 0.15274- (rtdr-100.0)*2310.0e-7;
if(y>= 0)
y= sqrt(y);
temp = (y-0.39083)/(-0.0001155) ;

FloatToStr(temp,opr);
Lcd_Out(1,1,lcd);

[B]Lcd_Out(1,1,[U][COLOR="#FF0000"]lcd[/COLOR][/U]);[/B]

Where did you get this "lcd" variable?

FloatToStr(temp,[COLOR="#FF0000"][B][U]opr[/U][/B][/COLOR]);

You should use this "opr" variable, which is where your result from the float to string conversion is stored.

Hope this helps.

Thank you Tahmid,i corrected my code with Lcd_Out(1,1,opr),but i get blank lcd and no pic microcontroller operation simulating on proteus.
