如果参数为0，则对应的浮点数和双精度数的结果分别是- 127和- 1023。
If the argument is zero, then the result will be -127 for a float and -1023 for a double.

The variable $values is neither a node-set nor an IDN; it is just a sequence of atomic double-precision numbers.
双精度数是以类似的方式编码的，但是它使用52位的尾数和11位的指数来获得更高的精度。
Doubles are encoded in much the same way except that they use a 52-bit mantissa and an 11-bit exponent for higher precision.
对于财务应用程序(尤其是需要精确到最后一位的会计应用程序)，处理浮点数和双精度数时也需要格外小心。
Financial applications (and especially accounting applications that require accuracy to the last cent) also need to be exceedingly careful when manipulating floats and doubles.
除支持基本的字符串之外，您还可以存储布尔值、双精度数、浮点数、整型数、长整型数和字节数组(考虑序列化)。
In addition to basic string support, you can store booleans, doubles, floats, integers, longs, and byte arrays (think serialization).
例如，我曾经在Mandelbrot集合管理器看见过这种情况。在其中可以放大曲线图，让其落在最近的两个双精度数之间。
For instance, I've seen this come up in Mandelbrot set explorers where you can zoom in so far that the entire graph falls between the nearest two doubles.
double类型也可以表示为DOUBLEPRECISION，虽然为什么在需要双精度数字时要输入额外的单词，原因不明。
The double type can also be referred to as double precision, although it isn't clear why you would want to type the extra word every time you need a double-precision number.
Meschach有一个返回在0,1之间的随机双精度数的函数，它是Meschach的一个特色，可用于简化明显的踏脚石程序的编写。
One of the Meschach features that simplifies writing the obvious stepping stone programs is a function that returns a random double in 0, 1.
虽然Meschach有一个用1.0填充矩阵的函数，但不幸的是，它没有用一个任意的双精度数填充矩阵的函数，也没有用随机双精度数填充矩阵的函数。
Although Meschach has a function that fills a matrix with 1.0s, it unfortunately lacks a function for filling a matrix with an arbitrary double or with random doubles.
