[issue11967] Left shift and Right shift for floats

[David Albert Torpey]

New submission from David Albert Torpey <dtorp at users.sourceforge.net>:

I would like to left and right shift floats as a fast way to multiply or divide by a power of 2 without rounding error.  The only way to do that now is t=frexp(x) and y=ldexp(t[0],t[1]+2).  But would be better to type y=x<<2.  Thank you.
