非法使用十进制小数点。
和大多数十进制小数不能用二进制表示的类型。
And most decimal fractions cannot be represented by a binary type.
用基数乘十进制小数。用基数乘十进制小数。
十进制小数中的点，表示从该点开始，值就从0的正次幂变成0的负次幂。
A dot written in a decimal number to indicate where the place values change from positive to negative powers of 0.
许多语言会直接显示这个数字，而不将真实结果转换回最接近的十进制小数。
Many languages then display that number instead of converting the actual result back to the closest decimal fraction.
十进制小数中的点，表示从该点开始，值就从10的正次幂变成10的负次幂。
A dot written in a decimal number to indicate where the place values change from positive to negative powers of 10.
根据各种习惯，十进制小数点可用逗号、号或在数字符的半高位置上加上一个点来表示。
The decimal point may be represented, according to various conventions, by a comma, by a period, or by a point at the mid-height of the digits.
在标准的十进制中，几乎所有实数都不能用有限小数表示。
In the standard decimal representation, almost all real numbers do not have a terminating decimal representation.
十进制模块提供做小数数学优良的设施，但它比浮点较为繁琐的使用。
The decimal module provides excellent facilities for doing decimal math, but it is somewhat more cumbersome to use than floating-point.
十进制系统的基数为10，且从小数点每左进一位或者右退一位，其权增加或者减少10的幂次。
In the decimal system the base or radix is 10, and each position to the left or right of decimal point presents an increased or decreased weight as power of 10.
句号也可用作十进制的小数点。
有关这是“自然确切小数”这是很好的使用十进制值。
For values which are "naturally exact decimals" it's good to use decimal.
编辑浮点值时，由于要将小数部分从十进制转换为二进制，因此所得的结果可能存在微小误差。
Editing floating-point values can result in minor inaccuracies because of decimal-to-binary conversion of fractional components.
在这里，原来的值将不会是“小数点精确”下手，所以它不是重要的了预期的效果，以保持“十进制精度”。
Here, the original values won't be "decimally accurate" to start with, so it's not important for the expected results to maintain the "decimal accuracy".
