Nastier input tests

• Input: style="font-size: 70% ;"
• Result:
• Input: 'style="font-size: 70% ;"'
• Result:
• Input: `style="font-size: 70% ;"`
• Result:
• Input: =70%
• Result:

Yeah, it dies on contact with =. Can it be escaped? (see below: use |1=)

• Input: {{=}}70%
• Result: 70
• Input: style{{=}}"font-size: 70% ;"
• Result: 70
• Input: <span style{{=}}"font-size: 70%;">
• Result: 70
• Input: <span style<nowiki>=</nowiki>"font-size: 70%;">
• Result: 70

Yes, though only with {{=}}; it chokes on <nowiki>...</nowiki>. Though this points out the relative uselessness of trying to use this on strings this complicated, since -70 is the opposite of the desired output, 70. It needs to be able to discern with - is directly associated with a numeral (or perhaps a ., since while -.7 is crappy style, it's still a technically valid way to write -0.7.

Try: |1=

• Input: 1=70%
• Result: 70 Y

• Input: <span class="nowrap"><span data-sort-value="7001123000000000000♠"></span>12.3</span> (produced by {{val|12.3}})
• Result: 7.001123e+18

After upgrade to match more narrowly

• Input: style{{=}}"margin-left: 10% ;"
• Result: 10
• Input: style{{=}}"margin-left: -10% ;"
• Result: -10
• Input: Weasels - 12. Chickens - 72.
• Result: 12
