Hi, I wonder why isn’t \<\< (with \>\> and \>\>\>) defined for float (32 and 64). Is it because of flaoting point vs fixed?

Yup, basically. This isn’t specific to Julia; see: [c - Left shift Float type - Stack Overflow](https://stackoverflow.com/questions/9315539/left-shift-float-type)

Note also that you can use the `exp2` function to multiply or divide a floating-point number by a power of 2.
