Editing Division by two (section)

==Binary floating point==
In binary [[floating-point arithmetic]], division by two can be performed by decreasing the exponent by one (as long as the result is not a [[subnormal number]]). Many programming languages provide functions that can be used to divide a floating point number by a power of two. For example, the [[Java (programming language)|Java programming language]] provides the method <code>java.lang.Math.scalb</code> for scaling by a power of two,<ref>{{cite web
