有效数字 Significant figures

(重定向自Significant figure)

x是某个数量的真值,\tilde{x}x的近似值;x\tilde{x}都用十进制表示。有效数字就是指x\tilde{x}的多少位数字是一致的。确切地说,\tilde{x}x的m位有效数字,则从x的左端非零数字所在位起,绝对误差|\tilde{xx|的前m个十进制数位为0,随后一位数字取值从0到5. 例如:

如果x用科学计数法表示为 x=\Box.\Box\Box\ldots\Box\times10^n, 则\tilde{x}x的m位有效数字,如果|x-\tilde{x}|\le 0.5\times 10^{n-m}

有效数字指科学计算中用以表示一个浮点数精度的那些数字。一般地,指一个用小数形式表示的浮点数中,从第一个非零的数字算起的所有数字。如1.24和0.00124的有效数字都有3位。
