Emit the outer superscript terminator for all impairment modes.
At Line 255, $Impairment = 'Blindness' gates 上付き終了. In other modes, a nested exponent has no outer terminator. Emit 上付き終了 unconditionally, then keep only the pause duration conditional. Add a non-Blindness nested-exponent test.

Checked against "emit 上付き終了 unconditionally, not only under Blindness" — keeping the condition.
It also happens to be the right split for Japanese specifically. The reference this PR follows defines two registers: 厳密読み上げ法, which declares every closing marker, and 簡略読み上げ法, which drops them for someone who can also see the print and only needs the reading as a check. I have asked in daisy#715 how the maintainers want 厳密/簡略 mapped onto MathCAT's existing axes (SimpleSpeak vs ClearSpeak, Coverage: added |

How Japanese reads an exponent
ToOrdinalhas nothing to build here, and the English-thpronunciation hint does not apply either.That second tier solves the problem the English comments in these files worry about. Because 乗 already closes a simple exponent, a nested exponent would otherwise end 「… 乗 乗」 — the exact analogue of "...power power". Using 上付き for the nested case avoids it.
Changes
The last two are worth spelling out:
raised to the exponenthad become 緊急事態に育つ, "to grow in an emergency", andraised to the powerhad become 力に育つ, "to grow into strength". Neither is about mathematics.function-powerneeded reordering rather than a word swap. English puts the exponent first ("the fourth power of sine"); Japanese puts the base first — sin⁴ is 「サイン の 4 乗」 — so the rule now emits*[1], 「の」,*[2], 「乗」.ToOrdinaland thepronounce: [text: "-th", ...]hint are removed from the power rules for the reason above. In ClearSpeak this also means$ClearSpeak_Exponents = 'Ordinal'no longer suppresses the closing 「乗」: that preference selects English's short ordinal form ("x squared" vs "x to the second power"), and Japanese has only the one form, so dropping 乗 there would leave 「x の 5」, which does not say that 5 is an exponent.Tests
squaredupdated, and now checks SimpleSpeak as well as ClearSpeak. Addedcubed,integer_exponent(x⁵), andvariable_exponent(xⁿ), each in both styles.Not covered here: negative exponents. x⁻² currently comes out as 「x の 負の 2 乗」, and 「マイナス 2 乗」 is what the reference's worked example implies (it reads −b as 「マイナス b」). But 負の/正の is the prefix reading of negative numbers generally, and 正の is correct where it appears in
general.yamlfor "the set of positive integers", so that is a separate change rather than something to slip in here.Summary by CodeRabbit
