Explicitly converts an expression from one data type to the single data type.
CSng( expression )
This function controls the data type of a numeric expression explicitly. This
function forces single-precision arithmetic in cases in which currency or
integer arithmetic normally would occur.
CSng converts each Double value to a Single. Note that 75.3421115 is rounded down
to 75.34211, whereas 75.3421155 is rounded up to 75.34212.
X = CSng( 75.3421115 )
