S23, the numerical value of parameter is sorted.
Here can adopt several different methods to sort to the numerical value of parameter.The sort method providing in the present invention is as follows:
Numerical value after divided by precision of S231, calculating parameter and the error between the numerical value divided by precision and after rounding.For example, parameter value 1.153584563, precision position 0.1, after precision, rounding is downwards 11, the numerical value of parameter and round after numerical value between error be 0.53584563;
S232, according to mistake extent, parameter is sorted.Wherein, if error equates to sort according to the numerical values recited of raw parameter; If the numerical values recited of raw parameter equates, according to the order sequence of acquiescence.
For example, if the error of parameter a is greater than the error of parameter b, parameter a come parameter b before;
If the error of parameter a equals the error of parameter b, according to the size sequence of parameter a, b raw parameter numerical value;
If the former numerical value of parameter a is greater than parameter b, before parameter a comes parameter b;
If the former numerical value of parameter a equals parameter b, according to the order sequence of acquiescence; As a, b, c, d etc.
S24, complementary number: according to ranking results from big to small, the numerical value after a front R parameter is rounded adds 1;
S25, be multiplied by precision: the parameter result after complementary number (comprising the numerical value that adds 1 R numerical value and do not add 1 parameter after rounding) is multiplied by precision, the parameter after being blocked.
S3, the parameter after blocking are exported as final argument.
By the described parameter output intent output parameter blocking based on parameter, can meet the related request (with being a determined value) of correlation parameter output, can not affect the accuracy of parameter again, meet the truncation error of each parameter within the scope of 1 precision position, can also not affect the magnitude relationship between original parameter.
