The "one-half" symbol has its own code point as a precomposed character in the Number Forms block of Unicode, rendering as ½.. The reduced size of this symbol may make it illegible to readers with relatively mild visual impairment; consequently the decomposed forms 1 ⁄ 2 or 1 / 2 may be more appropriate.
Number Forms is a Unicode block containing Unicode compatibility characters that have specific meaning as numbers, but are constructed from other characters.They consist primarily of vulgar fractions and Roman numerals.

Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two, e.g. 1 / 8 = 1 / 2 3 . In Unicode, precomposed fraction characters are in the Number Forms block.
Thus "H₂O" (using a subscript 2 character) is supposed to be identical to "H 2 O" (with subscript markup). 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 possibility of setting prices including an odd half penny also made it more practical to retain the pre-decimal sixpence in circulation (with a value of 2 + 1 / 2 new pence) alongside the new decimal coinage. The halfpenny coin's obverse featured the profile of Queen Elizabeth II; the reverse featured an image of St Edward's Crown ...
