Binary scaling is currently used in the [[Discrete cosine transform|DCT]] used to compress [[JPEG]] images in utilities such as [[GIMP]].

Although floating point has taken over to a large degree, where speed and extra accuracy are required, binary scaling works on simpler hardware and is more accurate when the range of values is known in advance.{{Clarify|date=March 2016|post-text=→[[Talk:Binary scaling#Comparison with Floating Point|talk]]}}

This is because all the bits in a binary scaled integer are used for the precision of the value

whereas in floating point, some bits are used to define the scaling.
