When using casting, we explicitly instruct the compiler to interpret the float value as an integer, disregarding the decimal part and potential loss of precision.While C++ provides safer alternatives like static_cast, reinterpret_cast, const_cast, and dynamic_cast, the C-style cast using (...

1. 释义区别:- int: int是整数（integer）的缩写，代表整数类型。它指的是没有小数部分的数字。- float: float是浮点数（floating-point number）的缩写，代表浮点数类型。它指的是具有小数部分的数字。例句:- int: 我的年龄是25岁。 (My age is 25.)- float: 我的体重是63.5公斤。 (My ...

Float vs. Double and Int Float and double are similar types. Float is a single-precision, 32-bit floating point data type; double is a double-precision, 64-bit floating point data type. The biggest differences are in precision and range. Double: The double accommodates 15 to 16 digits, ...
