Numbers are all in IEEE double precision format.

数值全部采用IEEE双精度格式。

Rounds a double-precision floating-point value to the nearest integral value.

将双精度浮点值舍入为最接近的整数值。

Has both a single precision float type and double-precision double type.

语言有单精度和双精度两种浮点类型。

Gets the value of the column as a double-precision floating point number.

指定的列不包含双精度浮点数。

An inversion of the source, double-precision data can be called directly.

一个求逆的源程序，双精度型数据，直接调用即可。

For example, a business user might not know that double means a double-precision decimal.

例如，业务用户可能不知道 double 表示双精度小数。

Reads the current element and returns the contents as a double-precision floating-point number.

读取当前元素并将内容作为双精度浮点数返回。

Converts the value of the specified object to a double-precision floating-point number.

返回指定的双精度浮点数；不执行任何实际的转换。

Floating-point values in Python are always done in double precision; hence, Python float types correspond to doubles in a C-like language.

在Python 中，浮点值始终是按双精度处理的；因此Python 的float类型对应于C类语言中的双精度。

Converts the value of the specified decimal number to an equivalent double-precision floating-point number.

将指定的单精度浮点数的值转换为等效的双精度浮点数。
