"WebIf you really want to bit-shift a float, you could use a method called fixed-point. Say you want to hold the number 1.23 (and bit-shift it later). You would store 123 in an int, and every time you accessed the variable you would divide the value by 100: Code: ? 1 2 3 int i = 123; i = i << 3; printf("%f", i/100.0); I hope this helps. 05-24-2005 #3 " - C shifting bits

WebAn integer is usually 32-bits or 64-bits long, for example. An important thing to keep in mind is that shifting by 1 to the left is the same as multiplying by 2, while shifting to the right by 1 is the same as dividing by 2 then rounding down. C doesn't have a >>> operator, and shifting of negative numbers is undefined in C. More posts you may like
