Abstract: A post-processing is executed on a mantissa M and an exponent E of a floating point binary number as a result of subtraction for example, thereby to obtain a mantissa m and an exponent e of the result of the post-processing. Therefore, an output (E-1) of a decrementer and an output (amount of cancelling of mantissa LSA) of an advancing 1 detecting circuit are entered into a minimum value selecting circuit. The minimum value selecting circuit is adapted to set a shift amount SH to (E-1) and a magnitude-relation judging signal CR to 1 when (E-1) is smaller than LSA (that is, when a denormalize processing is required). When (E-1) is not smaller than LSA (that is, when a normalize processing is required), SH is set to LSA and CR is set to 0. A left shifter is adapted to supply, as the mantissa m of the result, a value obtained by executing a left shift processing having a shift amount SH on the mantissa M.

Abstract: At a format conversion of a floating point number from double-precision to single-precision, a temporary exponent e.sub.1 is obtained by subtracting a double-precision bias B.sub.d from an exponent E of an operand and by adding a single-precision bias B.sub.s thereto. A mantissa M of the operand is shifted to right by a number obtained by adding 1 to an absolute value of the exponent e.sub.1 when e.sub.1 .ltoreq.0. When e.sub.1 >0, the mantissa M is not shifted. the result is rounded to a 23-bit length. When no carry is caused, the rounded value and 0 (when e.sub.1 .ltoreq.0) or e.sub.1 (when e.sub.1 >0) are respectively a mantissa and an exponent to be obtained. The rounded value and e.sub.1 +1 are regarded as a conversion result when e.sub.1 =0 and a carry is caused. A value obtained by shifting the rounded value to right by 1 bit and e.sub.1 +1 are selected when e.sub.1 >0 and a carry is caused.

Abstract: An approximate solution Ya of a function F with respect to a given value X is derived by referring to a relation Y=F(X) at an accuracy at which an error between the approximate solution Ya and an infinitely precise solution Y is smaller than a weight of a digit in a place lower than a lowest place of significant digits for a final solution by two places. The approximate solution Ya is rounded to an interim solution Yr equal to one of possible interim solutions which is closest to the approximate solution Ya. A value Xr is derived from the interim solution Yr and an inverse function F.sup.-1 by referring to a relation Xr=F.sup.-1 (Yr). A sticky digit S is set to 0, 1, or -1 in response to the relation between the magnitudes of the values X and Xr and other information. The sticky digit S is added to a place immediately lower than a lowest place of the interim solution Yr. A result of this addition is rounded in a designated rounding mode to obtain the final solution.
