ivoid setup() {

}

void loop() {

What you want is something like

float a,b,c,d;
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
a=Serial.parseFloat();
b=Serial.parseFloat();
c=Serial.parseFloat();
d=Serial.parseFloat();
}

void loop() {
// the variables have gotten get those values
// a=255;
// b=-15;
// c=10;
// d=8.5
}

Have a look at Serial Input Basics. It also includes a parse example.
