Convert.ToSByte Method (Single)
.NET Framework (current version)
Converts the value of the specified single-precision floating-point number to an equivalent 8-bit signed integer.
This API is not CLS-compliant.
Assembly: mscorlib (in mscorlib.dll)
<CLSCompliantAttribute(False)> Public Shared Function ToSByte ( value As Single ) As SByte
Parameters
- value
-
Type:
System.Single
The single-precision floating-point number to convert.
Return Value
Type: System.SBytevalue, rounded to the nearest 8-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.
| Exception | Condition |
|---|---|
| OverflowException | value is greater than SByte.MaxValue or less than SByte.MinValue. |
The following example attempts to convert each element in an array of Single values to a signed byte.
Dim values() As Object = { True, -12, 163, 935, "x"c, "104", "103.0", "-1", _ "1.00e2", "One", 1.00e2} Dim result As SByte For Each value As Object In values Try result = Convert.ToSByte(value) Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.", _ value.GetType().Name, value, _ result.GetType().Name, result) Catch e As OverflowException Console.WriteLine("The {0} value {1} is outside the range of the SByte type.", _ value.GetType().Name, value) Catch e As FormatException Console.WriteLine("The {0} value {1} is not in a recognizable format.", _ value.GetType().Name, value) Catch e As InvalidCastException Console.WriteLine("No conversion to a Byte exists for the {0} value {1}.", _ value.GetType().Name, value) End Try Next ' The example displays the following output: ' Converted the Boolean value True to the SByte value 1. ' Converted the Int32 value -12 to the SByte value -12. ' The Int32 value 163 is outside the range of the SByte type. ' The Int32 value 935 is outside the range of the SByte type. ' Converted the Char value x to the SByte value 120. ' Converted the String value 104 to the SByte value 104. ' The String value 103.0 is not in a recognizable format. ' Converted the String value -1 to the SByte value -1. ' The String value 1.00e2 is not in a recognizable format. ' The String value One is not in a recognizable format. ' Converted the Double value 100 to the SByte value 100.
