NProduct• NProduct[f, {i, imin, imax}] gives a numerical approximation to the product  .
• NProduct[f, {i, imin, imax, di}] uses a step di in the product. • NProduct can be used for products with both finite and infinite limits.
• NProduct[f, {i, ... }, {j, ... }, ... ] can be used to evaluate multidimensional products.
• NProduct[f, {i, imin, imax}] can be entered as  .
•  can be entered as  prod or \[Product].
• See also: NSum.
