The following example converts each element in an array of Double values to a Single value.
Dim values() As Double = { Double.MinValue, -1.38e10, -1023.299, -12.98, _ 0, 9.113e-16, 103.919, 17834.191, Double.MaxValue } Dim result As Single For Each value As Double In values result = Convert.ToSingle(value) Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.", _ value.GetType().Name, value, _ result.GetType().Name, result) Next ' The example displays the following output: ' Converted the Double value '-1.79769313486232E+308' to the Single value -Infinity. ' Converted the Double value '-13800000000' to the Single value -1.38E+10. ' Converted the Double value '-1023.299' to the Single value -1023.299. ' Converted the Double value '-12.98' to the Single value -12.98. ' Converted the Double value '0' to the Single value 0. ' Converted the Double value '9.113E-16' to the Single value 9.113E-16. ' Converted the Double value '103.919' to the Single value 103.919. ' Converted the Double value '17834.191' to the Single value 17834.19. ' Converted the Double value '1.79769313486232E+308' to the Single value Infinity.
