float

System.Single
Single Precision Floating Point (-3.402 E 38 to 3.4.02 E 38)
8 significant digits.
The default value is 0.

float myFloat; 
System.Single myFloat; 

Explicit Data Type

You can append literal constants with the letter "F" or "f" when you need to specify this type of literal.

float myFloat = 1.6f                          ' suffix is necessary  
float myFloat = 1.6F                          ' suffix is necessary  

Converting

// Float to Double 
float myFloat = 1.6F; 
double myDouble = myFloat;                    ' implicit  

// Float to Decimal 
float myFloat = 1.6F; 
decimal myDecimal = (int)myFloat;             ' explicit  

// Float to Integer 
float myFloat = 1.6F; 
int myInt = (int)myFloat;                     ' explicit  

Examples

float myFloat = (float)4/3                    '= 1.33333  

Console.WriteLine( 4/3 );                     '= 1  
Console.WriteLine( (float)4/3 );              '= 1.33333  

float.NaN                                     'NaN  
float.IsNaN                  
float.PositiveInfinity                        '+∞  
float.NegativeInfinity                        '-∞  
-0.0f                                         '-0  

float myFloat = 1.0F / 0.0F                   'Positive infinity  
System.Diagnostics.Debug.Print myFloat        '= Infinity  

float myFloat = 0.0F / 0.0F                   'Not a Number  
System.Diagnostics.Debug.Print myFloat        '= NaN
