- What is the difference between float and double? - Stack Overflow
I've read about the difference between double precision and single precision However, in most cases, float and double seem to be interchangeable, i e using one or the other does not seem to affec
- c - float vs. double precision - Stack Overflow
The 53 bits of double s give about 16 digits of precision The 24 bits of float s give about 7 digits of precision
- c++ - double and accuracy - Stack Overflow
A double typically provides 16 (±1) decimal digits Your example shows this: 4 8 12 16 v v v v 0 947368421052631578 long double 0 947368421052631526 double The answers agree to 16 digits This is what should be expected Also, note that there's no guarantee in the C Standard that a long double has more precision than a double The last decimal digit (16th or 17th) is not necessarily accurate
- C语言中,double**和double (*) [5]有什么区别?怎么理解? - 知乎
double** 是指向 double* 类型的指针类型。 区别不是很显然的吗? double [5] 类型能隐式转换成 double* 类型,但它们不是同一类型。 可以考虑一下 short 和 long 这两种类型是能相互隐式转换的,但它们显然没有因此变成同一类型。
- c语言中float、double的区别和用法? - 知乎
C语言中,float和double都属于 浮点数。区别在于:double所表示的范围,整数部分范围大于float,小数部分,精度也高于float。 举个例子: 圆周率 3 1415926535 这个数字,如果用float来表示,最多只能精确到小数点后面的6位。而double大约能精确到小数点后面的15位左右。具体精确到几位,跟所用的 编译器
- What exactly does Double mean in java? - Stack Overflow

- c++ - Double precision - decimal places - Stack Overflow
From what I have read, a value of data type double has an approximate precision of 15 decimal places However, when I use a number whose decimal representation repeats, such as 1 0 7 0, I find tha
