摘要：PURPOSE:To decide a meaningless result and to correct the decided result to zero by previously specifying the number of significant figures for column truncation in the number of significant digits of a mantissa part to be frequently generated at the time of adding/subtracting adjacent values in the order in operation using the approximation of a floating point for the expression of a real number. CONSTITUTION:An
truncated怎么解决
addition/subtraction input/output index difference outputted from an
addition/subtraction input/output index difference outputted from an
addition/subtraction input/output index difference detector (e) is inputted to a correction deciding device (g) together with an effective addition/subtraction
input/output index difference outputted from an effective addition/subtraction
input/output index difference specifying device (f). When the addition/ subtraction I/O index difference is larger than the effective addition/subtraction I/O index difference, a correction deciding device (g) sends a correction command to a correction selecting device (h), and in the other case, no correction c
ommand is sent. When a value obtained by floating point addition/subtraction processing is inputted from an addition/ subtraction output side index part segmenting device (g) to the device (h) and the
correction command is not sent from the device (g), the value is outputted, and the other case, a zero value included in the device (h) is outputted. Thus, the generation of column truncation can be prevented.
