double integer range

1. ScopeThe float and double ranges are determined by the number of digits of the index.The float index has eight digits, while the double index has 11 digits. The distribution is as follows:Float:1bit (symbol bit) 8 bits (index bit) 23 bits (tail

IEEE754 the representation of floating-point numbers. The expression range of float type data in C language is -3.4*10^38~+3.4*10^38. Double is -1.7*10^-308~1.7*10^308,long double for -1.2*10^-4932~1.2*10^4932. Type Number of bits

double and float are floating point types. Doubles (double type) are more accurate than float (single-precision) data and occupy more space. Double precision is twice times that of float, so a double is often used for more precise calculations.
