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 WebThe bit shifting operators do exactly what their name implies.
