    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

    CD5-CD72 is thought to mediate B cell-B cell interaction. What differentiates B1 cells from other B cells is the variable existence of CD5, CD86, IgM and IgD. [1] B-1 B cells, in the mouse, can be further subdivided into B-1a (CD5 +) and B-1b (CD5 −) subtypes. Unlike B-1a B cells, the B-1b subtype can be generated from precursors in the adult ...

    However, one may also require a 0 = b 1, a 1 = b 0, and a n = b n for all n > 1, thus getting another, non-canonical, natural isomorphism. Moreover, every permutation of the index set { 0, 1, 2, ... } leads to a natural isomorphism; they are uncountably many. Another example.

    It is an open research issue whether some programmers prefer shorter identifiers because they are easier to type, or think up, than longer identifiers, or because in many situations a longer identifier simply clutters the visible code and provides no perceived additional benefit. Brevity in programming could be in part attributed to:
