WebSep 22, 2013 · Add a comment. -2. You'd have to transform the float to something else first. Such as: float f = 128; f = (float) ( ( (int) f) << 1 ); And in the above, f should be 256.0. Now obviously this is problematic if you start with 128.4 as the cast will drop the .4. You may not want to be using a float in first place. Share.

After 14 times left shifting you get. 1000 0000 0000 0000. Now right shift the value 33602, 2 times as required. You get. WebAug 29, 2024 · A mask defines which bits you want to keep, and which bits you want to clear. Masking is the act of applying a mask to a value. This is accomplished by doing: Below is an example of extracting a subset of the bits in the value: Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits.
