Webfloat f = 0.6; unsigned char data [sizeof (float)]; memcpy (data, f, sizeof (f)); You don't even need to make this copy, though. You can directly pass a pointer to the float to your write-to-USB function, and tell it how many bytes to copy ( sizeof (f) ). You'll need an explicit cast if the function takes a pointer argument other than void*. WebThere are the following data types in C language. Types Data Types; Basic Data Type: int, char, float, double: ... Basic Data Types. The basic data types are integer-based and floating-point based. C language supports both signed and unsigned literals. The memory size of the basic data types may change according to 32 or 64-bit operating system. WebC - Constants and Literals. Constants refer to fixed values that the program may not alter during its execution. These fixed values are also called literals. Constants can be of any of the basic data types like an integer constant, a floating constant, a character constant, or a string literal.
