Controls quad precision in simplex
  Type: int
  Default value: -1
  Minimum value: -1
  Maximum value: 1

Enables or disables quad precision computation in simplex. The -1 default setting allows the algorithm to decide. Quad precision can sometimes help solve numerically challenging models, but it can also significantly increase runtime. Quad precision is only available on processors that support quadruple precision, e.g., common Intel processors. On other processors, the parameter has no effect.
