Original double value: 0.3333333333333333Converted float value: 0.33333334 In this example, we start by declaring adoublevariable nameddoubleValueand assigning it the value1.0 / 3.0. To convert thisdoublevalue to afloatusing direct casting, we employ the(float)syntax before thedoubleValuevariable. This...
