|
14 | * Unary plus operation.
|
15 | * Boolean values and strings will be converted to a number, numeric values will be returned as is.
|
16 | *
|
17 | * For matrices, the function is evaluated element wise.
|
18 | *
|
19 | * Syntax:
|
20 | *
|
21 | * math.unaryPlus(x)
|
22 | *
|
23 | * Examples:
|
24 | *
|
25 | * math.unaryPlus(3.5) // returns 3.5
|
26 | * math.unaryPlus(1) // returns 1
|
27 | *
|
28 | * See also:
|
29 | *
|
30 | * unaryMinus, add, subtract
|
31 | *
|
32 | * @param {number | BigNumber | Fraction | string | Complex | Unit | Array | Matrix} x
|
33 | * Input value
|
34 | * @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}
|
35 | * Returns the input value when numeric, converts to a number when input is non-numeric.
