Datatype Conversion.
It is sometimes beneficial to convert a value from one type of data to another. Each of the conversion functions converts its parameter to an equivalent representation within its datatype. The conversion functions include int(), float(), char(), byte(), and others.

    char c;    // Chars are used for storing typographic symbols
    float f;   // Floats are decimal numbers
    int i;     // Ints are values between -32,768 and 32.767
    byte b;    // Bytes are values between 0 and 255

    void setup() {
      c = 'A';
      f = float(c);     // Sets f = 65.0
      i = int(f * 1.4); // Sets i to 91
      b = (c / 2);  // Sets b to 32
      Serial.begin(9600);
      Serial.println(c);
      Serial.println(f);
      Serial.println(i);
      Serial.println(b, DEC);
    }

    void loop() {

    }
