A floating-point processor with selectable subprecision includes a register configured to store a plurality of bits in a floating-point format, a controller, and a floating-point mathematical operator. The controller is configured to select a subprecision for a floating-point operation, in response to user input. The controller is configured to determine a subset of the bits, in accordance with the selected subprecision. The floating-point operator is configured to perform the floating-point operation using only the subset of the bits. Excess bits that are not used in the floating-point operation may be forced into a low-leakage state. The output value resulting from the floating-point operation is either truncated or rounded to the selected subprecision.
