One may round half up (or round half toward positive infinity), a tie-breaking rule that is widely used in many disciplines. [citation needed] That is, half-way values of x are always rounded up. If the fractional part of x is exactly 0.5, then y = x + 0.5
A half-way model is an immersion of the sphere in , which is so-called because it is the half-way point of a sphere eversion.This class of eversions has time symmetry: the first half of the regular homotopy goes from the standard round sphere to the half-way model, and the second half (which goes from the half-way model to the inside-out sphere) is the same process in reverse.
For example, to round 1.25 to 2 significant figures: Round half away from zero rounds up to 1.3. This is the default rounding method implied in many disciplines [citation needed] if the required rounding method is not specified. Round half to even, which rounds to the nearest even number. With this method, 1.25 is rounded down to 1.2.
Apart from in mathematics articles, consider rounding to a reasonable resolution instead (e.g. a half farthing ≈£0.00052 not £0.0005208 3, an inch ≈0.333 palms not 0. 3 palms), or showing initial repeats before the overbar (e.g. 0.33 3). If overbars are used, consider explaining the notation on first use.
|-N (where -N is a negative number) replaces N digits before the decimal mark with zero (round output to nearest 10 N). |sigfig=N (where N is a positive number) to specify the number of significant digits (round output to N significant figures). |round=5 to round the output to the nearest multiple of 5. The round value can be 0.5, 5, 10, 25 or ...

There are two types of vowel rounding: protrusion and compression. [3] [4] [5] In protruded rounding, the corners of the mouth are drawn together and the lips protrude like a tube, with their inner surface visible. In compressed rounding, the corners of the mouth are drawn together, but the lips are also drawn together horizontally ("compressed ...
