If you assume that a reader of those docs may know what the FP mantissa is, then the solution is not to remove the word "mantissa" from there, but to add a link to Wikipedia page, or/and to just show an image like: http://en.wikipedia.org/wiki/File:IEEE_754_Double_Floating_Point_Format.svg If you want to use a function about floating point approximations you need to know how a FP is represented.
