Need help with floating point into array formatting

itoa() worked, tried it one of 7 places where it can be used.
Would ftoa() work similar?
ftoa - C++ Forum
I don't see how you limit it to one or two decimal places tho.

There is no 'ftoa()'.
Try dtostrf(). Here's a simple example of it's use:-

void setup()
{
    //  dtostrf(val, width, precision, buffer);

    Serial.begin(115200);
    double dVal = 123.4567;
    char buffer[10];
    dtostrf(dVal, 5, 2, buffer);  // Prints "123.46"
    Serial.println(buffer);

    dtostrf(dVal, 4, 2, buffer);  // Prints "123.46"
    Serial.println(buffer);

    dtostrf(dVal, 0, 3, buffer);  // Prints "123.457"
    Serial.println(buffer);

    dtostrf(dVal, 6, 2, buffer);  // Prints "123.46"
    Serial.println(buffer);

    dtostrf(dVal, 7, 2, buffer);  // Prints " 123.46"
    Serial.println(buffer);

    dVal=0.12345;
    dtostrf(dVal, 0, 2, buffer);  // Prints "0.12"
    Serial.println(buffer);
}

void loop(){}

Edit:
Why twice? :-

digitalWrite (cs0, LOW); 
digitalWrite (cs0, LOW);
