Convert.ToSingle Method (Double)

Parameters

• value
  Type: System.Double
  A double-precision floating point number.

Return Value

Type: System.Single
A single-precision floating point number equivalent to the value of value.
value is rounded using rounding to nearest. For example, when rounded to two decimals, the value 2.345 becomes 2.34 and the value 2.355 becomes 2.36.
