9 | * Create a string or convert any object into a string.

11 | *
|
12 | * Syntax:
|
13 | *
|
14 | * math.string(value)
|
15 | *
|
16 | * Examples:
|
17 | *
|
18 | * math.string(4.2) // returns string '4.2'
|
19 | * math.string(math.complex(3, 2) // returns string '3 + 2i'
|
20 | *
|
21 | * const u = math.unit(5, 'km')
|
22 | * math.string(u.to('m')) // returns string '5000 m'
|
23 | *
|
24 | * math.string([true, false]) // returns ['true', 'false']
