/**
|
|
* Interpolate values into a string template.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.print(template, values)
|
|
* math.print(template, values, precision)
|
|
* math.print(template, values, options)
|
|
*
|
|
* Example usage:
|
|
*
|
|
* // the following outputs: 'Lucy is 5 years old'
|
|
* math.print('Lucy is $age years old', {age: 5})
|
|
*
|
|
* // the following outputs: 'The value of pi is 3.141592654'
|
|
* math.print('The value of pi is $pi', {pi: math.pi}, 10)
|
|
*
|
|
* // the following outputs: 'hello Mary! The date is 2013-03-23'
|
|
* math.print('Hello $user.name! The date is $date', {
|
|
* user: {
|
|
* name: 'Mary',
|
|
* },
|
|
* date: new Date(2013, 2, 23).toISOString().substring(0, 10)
|
|
* })
|
|
*
|
|
* // the following outputs: 'My favorite fruits are apples and bananas !'
|
|
* math.print('My favorite fruits are $0 and $1 !', [
|
|
* 'apples',
|
|
* 'bananas'
