An information processor includes a memory; and a processor coupled to the memory and the processor configured to: acquire first statistical information about distribution of most significant bit position that is not a sign or least significant bit position that is not zero for each of a plurality of first fixed-point number data, the data being a computation result of the computation in the first layer; execute computation on a plurality of output data of the first layer according to a predetermined rule, in the computation in the second layer; and acquire second statistical information based on the predetermined rule and the first statistical information, and determine a bit range for limiting a bit width when a plurality of second fixed-point number data, the data being a computation result of the computation in the second layer, are stored in a register, based on the second statistical information.
