pascal float

In Pascal, the float data type represents floating-point numbers, which are numbers that can have decimal places. This data type is used to store real numbers in Pascal and allows for calculations involving fractional values. You can declare a variable of type float using the real keyword.

Here is an example of declaring and using a float variable in Pascal:

program FloatExample;
  myFloat: float;

  myFloat := 3.14;
  writeln('The value of myFloat is: ', myFloat);

In this example, we declare a variable myFloat of type float and assign it the value 3.14. We then use the writeln procedure to output the value of myFloat to the console. The output will be: "The value of myFloat is: 3.14".

You can perform arithmetic operations on float variables, such as addition, subtraction, multiplication, and division. Here is an example that demonstrates some basic arithmetic operations:

program FloatArithmetic;
  num1, num2, sum, difference, product, quotient: float;

  num1 := 5.5;
  num2 := 2.5;

  sum := num1 + num2;
  difference := num1 - num2;
  product := num1 * num2;
  quotient := num1 / num2;

  writeln('Sum: ', sum);
  writeln('Difference: ', difference);
  writeln('Product: ', product);
  writeln('Quotient: ', quotient);

In this example, we declare variables num1, num2, sum, difference, product, and quotient of type float. We assign values to num1 and num2 and then perform various arithmetic operations on them. The results are then printed to the console.
