Abstract
An arithmetic processing device includes a processor that calculates a constant multiplication value by multiplying a constant value obtained by dividing a first value by a natural logarithm of 2 and a data value, separates the constant multiplication value into an integer portion and a fractional portion, calculates a fractional power value corresponding to a value of the fractional portion, calculates an integer power value corresponding to a value obtained by multiplying a value of the integer portion by a second value, calculates a power addition value by adding the fractional power value and the integer power value, calculate a power subtraction value by subtracting the integer power value from the fractional power value, and calculate a division value by dividing the power subtraction value by the power addition value as a result of an execution of an arithmetic operation of a hyperbolic tangent function with the data value.
