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.


size(640, 360);
background(0);
noStroke();

textFont(createFont("SourceCodePro-Regular.ttf",24));

char c;    // Chars are used for storing alphanumeric symbols
float f;   // Floats are decimal numbers
int i;     // Integers are values between 2,147,483,647 and -2147483648
byte b;    // Bytes are values between -128 and 128

c = 'A';
f = float(c);      // Sets f = 65.0
i = int(f * 1.4);  // Sets i to 91
b = byte(c / 2);   // Sets b to 32

//println(f);
//println(i);
//println(b);

text("The value of variable c is " + c, 50, 100);
text("The value of variable f is " + f, 50, 150);
text("The value of variable i is " + i, 50, 200);
text("The value of variable b is " + b, 50, 250);
