WebThere are two bit shift operators in C++: the left shift operator << and the right shift operator >>. These operators cause the bits in the left operand to be shifted left or right by the number of positions specified by the right operand. 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 citizenship in india the hinduWebApr 13, 2024 · 1.
