Float size in c language
WebSep 29, 2024 · All floating-point numeric types are value types. They are also simple types and can be initialized with literals. All floating-point numeric types support arithmetic, … 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*.
