一、什么叫整数定位? 根据被乘数、乘数或被除数、除数的整数位数来确定积或商的整数位数,就叫整数定位。这种定位方法,一般在运算之后,在直接写到账面上时定位,而不是在算盘上定位。采用整数定位法,不管数字多么复杂,都能快速、准确定位。二、怎样确定数字的整数位数 1.纯整数如75、834等,看数字有几位就算几位。这两个数分别为2位、3位; 2.带小数如7.5、83.4、960.77等,则看整数的位数有几位就算几位。这三个致分别为1位、2位、3位; 3.纯小数如0.53、0.053、0.0078等,则看小数
First, what is the integer positioning? According to the multiplicand, multiplier or dividend, the integer number of divisors to determine the integer or quotient integer, called integer positioning. This positioning method, generally after the operation, when writing directly to the book when positioning, rather than positioning on the abacus. Using integer positioning method, no matter how complex the number, can quickly and accurately locate. Second, how to determine the number of digits 1 pure integer such as 75,834, see the number of a few even if a few. These two numbers were 2, 3; 2. With decimals such as 7.5,83.4,960.77, then look at the integer number of bits even if a few. The three caused were respectively 1, 2, 3; 3. Pure decimal such as 0.53,0.053,0.0078, etc., then look at the decimal
