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.
