Keywords are the words in a language that are used for some internal process or represent some predefined actions. float is a keyword that is used to declare a variable which can store a floating point value from the range of ±1.5 x 10-45 to ±3.4 x 1038. It is an alias of System.Single.
Syntax:
float variable_name = value;
float keyword occupies 4 bytes (32 bits) space in the memory. We use a suffix f or F with the value to represent a float value.
Example:
Input: -3629.4586F Output: num: -3629.458 Size of a float variable: 4 Input: 16345.6456f Output: Type of num: System.Single num: 16345.65 Size of a float variable: 4 Min value of float: -3.402823E+38 Max value of float: 3.402823E+38
Example 1:
// C# program for float keyword using System;
using System.Text;
class GFG {
static void Main( string [] args)
{
// variable declaration
float num = -3629.4586F;
// to print value
Console.WriteLine( "num: " + num);
// to print size
Console.WriteLine( "Size of a float variable: " + sizeof ( float ));
}
} |
Output:
num: -3629.458 Size of a float variable: 4
Example 2:
// C# program for float keyword using System;
using System.Text;
namespace geeks {
class GFG {
static void Main( string [] args)
{
// variable declaration
float num = 16345.6456f;
// to print type of variable
Console.WriteLine( "Type of num: " + num.GetType());
// to print value
Console.WriteLine( "num: " + num);
// to print size
Console.WriteLine( "Size of a float variable: " + sizeof ( float ));
// to print minimum & maximum value of float
Console.WriteLine( "Min value of float: " + float .MinValue);
Console.WriteLine( "Max value of float: " + float .MaxValue);
}
} } |
Output:
Type of num: System.Single num: 16345.65 Size of a float variable: 4 Min value of float: -3.402823E+38 Max value of float: 3.402823E+38
