In reality, many fonts that include these characters ignore the Unicode definition, and instead design the digits for mathematical numerator and denominator glyphs, [ 3 ] [ 4 ] which are aligned with the cap line and the baseline ...

The chemical formula of the water molecule, H 2 O, indicates that it contains two hydrogen atoms and one oxygen atom. A subscript is also used to distinguish between different versions of a ...
Then, the size of A5 paper is half of A4, i.e. 148 mm × 210 mm (5.8 in × 8.3 in). [ 6 ] [ 7 ] The geometric rationale for using the square root of 2 is to maintain the aspect ratio of each subsequent rectangle after cutting or folding an A-series sheet in half, perpendicular to the larger side.
These are usually handwritten on the paper containing the text. Symbols are interleaved in the text, while abbreviations may be placed in a margin with an arrow pointing to the problematic text. Different languages use different proofreading marks and sometimes publishers have their own in-house proofreading marks.
The three-by-five 三五判 (3×5 or 3/5), where the final size at 32K is slightly less than 3 by 5 sun, often given as 84 × 148 mm which would be c. 2.8 × 4.9 sun. The 4/6 standard has given rise to newer metric book-size standards, including:
