| Description | Considering that each number can be represented as a product, mantissa * 2exponent, where 1.0 ≤ mantissa < 2.0, the largest exponent occurring in a vector is returned. If the vector consisted of nothing but zeros, the exponent is returned as -231 (32-bit models) or -215 (16-bit models). |

| Return value | maximum exponent encountered. |
