Write a Double32_t to the buffer.
The following cases are supported for streaming a Double32_t type depending on the range declaration in the comment field of the data member:
| Case | Example |
|---|---|
| A | Double32_t fNormal; |
| B | Double32_t fTemperature; //[0,100] |
| C | Double32_t fCharge; //[-1,1,2] |
| D | Double32_t fVertex[3]; //[-30,30,10] |
| E | Double32_t fChi2; //[0,0,6] |
| F | Int_t fNsp; Double32_t* fPointValue; //[fNsp][0,3] |
In case A fNormal is converted from a Double_t to a Float_t In case B fTemperature is converted to a 32 bit unsigned integer In case C fCharge is converted to a 2 bits unsigned integer In case D the array elements of fVertex are converted to an unsigned 10 bits integer In case E fChi2 is converted to a Float_t with mantissa truncated precision at 6 bits In case F the fNsp elements of array fPointvalue are converted to an unsigned 32 bit integer Note that the range specifier must follow the dimension specifier. Case B has more precision (9 to 10 significative digits than case A (6 to 7 digits). See TBufferFile::WriteFloat16 for more information.

Write a Float16_t to the buffer.
The following cases are supported for streaming a Float16_t type depending on the range declaration in the comment field of the data member:
| Case | Example |
|---|---|
| A | Float16_t fNormal; |
| B | Float16_t fTemperature; //[0,100] |
| C | Float16_t fCharge; //[-1,1,2] |
| D | Float16_t fVertex[3]; //[-30,30,10] |
| E | Float16_t fChi2; //[0,0,6] |
| F | Int_t fNsp; Float16_t* fPointValue; //[fNsp][0,3] |
The range specifier has the general format: [xmin,xmax] or [xmin,xmax,nbits]
Lets assume an original variable float x: When using the format [0,0,8] (ie range not specified) you get the best relative precision when storing and reading back the truncated x, say xt. The variance of (x-xt)/x will be better than when specifying a range for the same number of bits. However the precision relative to the range (x-xt)/(xmax-xmin) will be worst, and vice-versa. The format [0,0,8] is also interesting when the range of x is infinite or unknown.
It is important to understand the difference with the meaning of nbits
See example of use of the Float16_t data type in tutorial double32.C

Write object to I/O buffer.
This function assumes that the value of 'actualObjectStart' is the actual start of the object of class 'actualClass' If 'cacheReuse' is true (default) upon seeing an object address a second time, we record the offset where its was written the first time rather than streaming the object a second time. If 'cacheReuse' is false, we always stream the object. This allows the (re)use of temporary object to store different data in the same buffer.
