Convert characters to their subscript and superscript counterpart
Numbers as subscript and superscript.
Ratio formatting

Description

One can make use of a block of Unicode characters to emulate subscript and superscript. Note that the subscript and superscript will be aligned with the baseline and the cap line respectively, and is thus not equivalent to sub.../sub and sup.../sup in HTML. Furthermore only a small subset of characters is supported.

This module allows one to map certain characters to their subscript and superscript counterpart, and furthermore makes it more convenient to transform a number (both positive and negative) to a Text that specifies this number in subscript and superscript.

Synopsis

toSub :: Char -> Maybe Char
toSup :: Char -> Maybe Char
asSub :: Integral i => i -> Text
asSup :: Integral i => i -> Text
ratioToUnicode :: Integral i => Ratio i -> Text

Convert characters to their subscript and superscript counterpart

toSub Source #

Arguments

:: Char	The given character to convert to its subscript counterpart.
-> Maybe Char	A character wrapped in a `Just` given the counterpart exists, `Nothing` otherwise.

Convert a set of characters to their subscript counterpart, given that characters exists.

toSup Source #

Arguments

:: Char	The given character to convert to its superscript counterpart.
-> Maybe Char	A character wrapped in a `Just` given the counterpart exists, `Nothing` otherwise.

Convert a set of characters to their superscript counterpart, given that characters exists.

Numbers as subscript and superscript.

asSub Source #

Arguments

:: Integral i
=> i	The number to convert.
-> Text	A `Text` value that contains the number as a sequence of subscript characters.

Convert a number (positive or negative) to a Text that specifies that number in subscript characters.

asSup Source #

Arguments

:: Integral i
=> i	The number to convert.
-> Text	A `Text` value that contains the number as a sequence of superscript characters.

Convert a number (positive or negative) to a Text that specifies that number in superscript characters.

Ratio formatting

ratioToUnicode Source #

Arguments

:: Integral i
=> Ratio i	The given `Ratio` value to format.
-> Text	The `Text` block that contains a textual representation of the `Ratio`.

Format a given Ratio object to a Text value that formats the ratio with superscript and subscript.
