In C++, both float and double data types are used for floating-point values. Floating-point numbers are used for decimal and exponential values. For example, // creating float type variables float num1 = 3.0f; float num2 = 3.5f; float num3 = 3E-5f; // 3x10^-5 // creating double type variables double num4 = 3.0; … See more Note: Unless you have a specific requirement, always use double instead of float, as floatvariables may be prone to introduce errors when working with large numbers. See more As mentioned above, float and double can also be used to represent exponential numbers. For example, C++ outputs exponential numbers and very large numbers in a format … See more We can specify the number of decimal points to print in cout by using the setprecision()function. This function is defined in the iomanip header file, which stands for input/output manipulation. See more Apart from float and double, there is another data type that can store floating-point numbers. This is known as long double. It usually occupies a space of 12 bytes (depends on … See more WebJun 17, 2024 · Now, the cast itself isn't technically the problem, it is the access of the value though dereferncing the different type (a.k.a type-punning) where you run afoul of the strict-aliasing rule (Section 6.5 (7) of the C11 Standard). The union of the float and uint32_t types give you a valid way of looking at the float bits through an unsigned type ...
