In some languages (though not generally in English) [ citation needed ] , a tilde-like wavy dash may be used as punctuation (instead of an unspaced hyphen or en-dash ) between two numbers , to indicate a range rather than subtraction or a hyphenated number (such as a part number or model number). For example, "12~15" means "12 to 15", "~3" means "up to three", and "100~" means "100 and greater". Japanese and other East Asian languages almost always use this convention, but it is often done for clarity in some other languages as well. Chinese uses the wavy dash and full-width em dash interchangeably for this purpose. In English, the tilde is often used to express ranges and model numbers in electronics , but rarely in formal grammar or in type-set documents, as a wavy dash preceding a number sometimes represents an approximation (see below).

I believe the proper name for the symbol in question is "Guillemet". This is what I was taught to call it more than 40 years ago in school. However, I must mention that even while being taught the appropriate name, the lesson came with a caveat... "most often we would hear it referred to as a 'greater than sign' or a 'less than sign' because in contemporary English Grammar the use of this symbol has fallen out of favor - but is used very widely in mathematical and algebraic expressions." (paraphrased) That lesson turned out to be very prophetic as it is more accurate now than it was then! Moreover, that prophecy was proved multiple times during the few hours and scores of websites & reference books upon which I relied to verify my memory. For it seems, in almost every instance, and regardless of the source's unique definition of the symbol, each example was accompanied with the common definition of "Greater Than Sign" and / or "Less Than Sign".
