Two values are returned: the first is a multiplier in the range 1/2 (inclusive) to 1 (exclusive) and the second is an integer exponent. The result is such that x = m*2^e. </description> <realm>Shared and Menu</realm> <args> <arg name="x" type="number">The value to get the normalized fraction and the exponent from.</arg> </args> <rets> <ret name="" type="number">m, multiplier - between 0.5 and 1</ret> <ret name="" type="number">e, exponent - always an integer</ret> </rets> </function>
