fullprof A complex variable has real and imaginary parts written in the form b(x) = n(x) + iv(x) for two real-valued functions n(x) and v(x)
这里的逻辑是parse将在输入流中首先查找一个字符串，然后查找整数，最后查找一个实数。
The logic is that parse will look first for a string, then for an integer, and finally for a real, in that order, in the input stream.
Derby对实数提供了多种格式的支持：单精度浮点、双精度浮点以及准确的算术表示，如表2所示。
Derby provides support for real Numbers in several formats: single-precision floating-point, double-precision floating-point, and an exact representation decimal, as presented in Table 2.
