Floating-Point and Double
Floating point numbers, also called floats, represent decimal numbers. We can declare a variable of type float using the float
keyword:
main.cs
1float myVariable = 3.14f;
The letter 'f
' in the value 3.14f
tells the compiler that the value is of type float. Values of the float
datatype should always be represented in this format.
The float
data type has a limited precision so it can only store 6 to 9 digits after the decimal. There is another datatype called double
which offers a higher precision:
main.cs
12345float myVar1 = 3.1415926535897f; double myVar2 = 3.1415926535897; Console.WriteLine(myVar1); // Output: 3.1415927 Console.WriteLine(myVar2); // Output: 3.1415926535897
As float
has a lower precision, the value 3.1415926535897
is automatically rounded off till its 7th decimal digit and the result is stored in the variable myVar1
.
Like int
and long
, we can also perform arithmetic operations on float
and double
values.
main.cs
12345float var1 = 1.14f; double var2 = 1.00; float var3 = 1.0f; double var4 = var1 + var2 + var3;
