Powers for unit 'in' are incorrect

[matthewbryant95]

Evaluation of 1/2 in results in 0.5 in^-1. For any other unit, 1/2 _unit_ evaluates to 0.5 _unit_.

Wow. This is still true, and definitely a bug. Presumably some side effect of the fact that 10 cm in feet produces 0.328 feet, but nevertheless, this should either report an error or produce a sensible result, not calmly produce nonsense.

can i work on this issue

[nkumawat34]

can you explain this issue little bit more with example.

Thanks @nkumawat34

console.log(math.evaluate('1/2 kg').toString()) 
// actual: 0.5 kg

console.log(math.evaluate('1/2 in').toString()) 
// actual:   0.5 in^-1 
// expected: 0.5 in

So, 1/2 in is evaluated as 1 / (2 * in) instead of (1/2) * in. This may be hard to pick up as a first issue, it requires diving into the expression parser and it's special rules around implicit multiplication and special parsing of "in" which is both a unit (inch) and an operator (like 2 meter in inch).
