IF ELSE STATEMENT NOT WORKING? if-else statement not working

So I'm facing this problem a lot in my code where the program is not getting into the if elseif else loop properly and just returning the same answer again and again.

void loop() {

double X_value = ((double)(analogRead(X_pin)-487))/540.00;
double Y_value = ((double)(529-analogRead(Y_pin)))/540.00;
  
double theta_rad = atan((double)Y_value/(double)X_value);
double theta_deg = ((double) theta_rad)*180.00/3.1416;

double temp = (double)abs(tan((double)theta_rad));
if (temp == 0.00) {
temp2 = 0.00;
} else {  
  double temp2 = min(temp,1.00/temp);
}

Serial.print("Theta = ");
Serial.print(theta_deg);
Serial.print("\n");
Serial.print("temp 2 = ");
Serial.print(temp2);
Serial.print("\n");

delay(1000);

}

The answer keeps on coming 0 even when temp is non zero.

If anyone knows the reason please help...
