| Function | Smallest exponent within one vector |
|
| Syntax C/C++ | #include <VFstd.h>
int VF_minexp( fVector X, ui size );
(similarly VD_, VE_)

| C++ VecObj | #include <OptiVec.h>
int vector<T>::minexp(); |

|
| Description | Considering that each number can be represented as a product, mantissa * 2exponent, where 1.0 <= mantissa < 2.0, the smallest or most negative exponent occurring in a vector is returned. If the absolutely smallest number was zero, the exponent is returned as -231 (32-bit models) or -215 (16-bit models). |

|
| Return value | minimum exponent encountered. |
