Customizing fraction exponent size in Typst

The forum suggests using math.inline(text(size: ...)) to scale the size of exponents. For Typst, you can try wrapping the exponent in math.inline, math.display, or use text(size:) for on-the-fly adjustments. For example, to adjust the size of (343/216)^(2/3), you could use $(343/216)^(math.inline(2/3)).

Clarifying syntax for math expressions in Typst

In Typst, since it's still in math mode, I think functions like text(size: ...) can be used within math syntax without needing #. However, to pass code expressions like text(size: ...), the # might be required. A forum snippet suggests using bigsuper(x) in math mode without the hash, like $(343/216)^bigsuper(2/3).

Understanding math mode syntax and fraction handling in Typst

In Typst, it seems you can define bigsuper in code mode and call it in math mode without using #, since math mode treats identifiers as variables. If you want a larger fraction but not an entire exponent, you can try using inline(2/3) or display(2/3). Typst uses frac(a, b) for fractions, but a/b will render as a fraction too.

Handling exponents and fractions when customizing size in Typst

In Typst, a / b produces a fraction with a horizontal line in math mode, similar to LaTeX. To make exponents larger, you can use inline(...) or display(...). There's also a cramped parameter—by default, it's true for scripts, but setting it to false might enlarge fractions. Would suggest using inline(body, cramped: false) to make exponents bigger.

Proposing ways to adjust exponent size in Typst

To adjust exponent size, use inline(...) or display(...) to change the style, like $(343/216)^(inline(2/3))$. You can also fine-tune size using text(size: ...) with em units. For global changes, math.frac or math.attach could be used. I'll provide a simple snippet and mention the slashion package for readable slash fractions.

Customizing sizes for fraction exponents in Typst

In Typst, superscripts default to script size. To adjust the size of exponents (e.g., fractions), use inline(...) or display(...) for resizing. For example, you

在 Typst 里，上标/下标默认会进入 script（更小）尺寸（“上标套上标”会变成 sscript 更小）。所以当你的指数是 2/3 这种“分数指数”时，默认就容易显得太小、太挤。 (Typst)

1) 最简单：把指数强制成更大的数学尺寸（推荐）

用 inline(...)（或更大一点用 display(...)）包住指数：

typst
$(343/216)^(2/3)$              // 默认：指数是 script 尺寸
$(343/216)^(inline(2/3))$       // 指数强制为 inline 尺寸（更清晰）
$(343/216)^(display(2/3))$      // 指数更大（接近陈列公式尺寸）

display/inline/script/sscript 这些就是 Typst 提供的“强制数学尺寸”函数。 (Typst)

2) 需要“自定义到具体倍率”：用 text(size: ...) 微调

论坛里一个很实用的写法是先做个小函数，把指数调到你想要的倍率（比如 0.85em）：

typst
#let bigsuper(x) = math.inline(text(size: 0.85em, x))

$(343/216)^(2/3)$
$(343/216)^bigsuper(2/3)$

你可以把 0.85em 改成 0.9em、1em 等来精确控制。 (Typst Forum)

3) 仍然觉得“分数上下太挤”时：试试 cramped

这些尺寸函数都有 cramped 参数；它控制在“脚本环境”里是否采用更“压扁”的高度策略。比如你想保持 script 大小但稍微松一点：

typst
$(343/216)^(script(2/3, cramped: false))$

参数说明见官方文档。 (Typst)

如果你告诉我你现在想要的效果是：“指数整体变大” 还是 “分数上下间距更松”，我可以给你一套更贴合的推荐写法（含可复用的全局 show 规则/只针对分数指数生效的规则）。
