PHP has a decimal type, which doesn't have the "inaccuracy" of floats and doubles, so that 2.5 + 2.5 = 5 and not 4.999999999978325 or something like that.
所以我想知道 C 或 C++ 是否有这样的数据类型实现?
So I wonder if there is such a data type implementation for C or C++?
推荐答案
是:
C++ 有任意精度的库. 一个很好的例子是 GNU 多精度算术库.
There are arbitrary precision libraries for C++.
A good example is The GNU Multiple Precision arithmetic library.
