It works with double inputs larger than 2^53-1, or char inputs with exponents.
num2vpi converts A into a vpi class variable using the exact bit representation of the A elements.
For single and double floating point inputs, num2vpi uses the FEX submission num2strexact to do the basic conversion.
For uint64 and int64, num2vpi does the conversion in two uint32 pieces since vpi handles uint32 inputs but not uint64 or int64 inputs.
The int64 conversion uses the typecast function. For logical inputs, num2vpi does a simple conversion to uint8 first, since vpi handles uint8 inputs but not logical inputs.
For char inputs, each row is interpreted as a single number. Decimal points and exponents are allowed as long as the result is an integer.
For all other input types, the input is simply passed on through to vpi to do the conversion.
