Datatype Functions
DoubleToShort
Converts the given double value to a short value
DoubleToByte
Converts the given double value to a byte value
DoubleToFloat
Converts the given double value to a float value
DoubleToLong
Converts the given double value to a long value
ToShort
Converts the given value to a short value. This function converts any value to a short value, thus it is more time consuming than the DoubleToShort function for double values.
ToByte
Converts the given value to a byte value. This function converts any value to a byte value, thus it is more time consuming than the DoubleToByte function for double values.
ToFloat
Converts the given value to a float value. This function converts any value to a float value, thus it is more time consuming than the DoubleToFloat function for double values.
ToLong
Converts the given value to a long value. This function converts any value to a long value, thus it is more time consuming than the DoubleToLong function for double values.
