/**
|
|
* Change the unit of a value.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.to(x, unit)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.to(math.unit('2 inch'), 'cm') // returns Unit 5.08 cm
|
|
* math.to(math.unit('2 inch'), math.unit(null, 'cm')) // returns Unit 5.08 cm
|
|
* math.to(math.unit(16, 'bytes'), 'bits') // returns Unit 128 bits
|
|
*
|
|
* See also:
|
|
*
|
|
* unit
|
|
*
|
|
* @param {Unit | Array | Matrix} x The unit to be converted.
|
|
* @param {Unit | Array | Matrix} unit New unit. Can be a string like "cm"
|
|
* or a unit without value.
|
|
* @return {Unit | Array | Matrix} value with changed, fixed unit.
