|
* Calculate the value of subtracting 1 from the exponential value.
|
||
|
|
* For matrices, the function is evaluated element wise.
|

|
|
*
|
||
|
|
* Syntax:
|
||
|
|
*
|
||
|
|
* math.expm1(x)
|
||
|
|
*
|
||
|
|
* Examples:
|
||
|
|
*
|
||
|
|
* math.expm1(2) // returns number 6.38905609893065
|
||
|
|
* math.pow(math.e, 2) - 1 // returns number 6.3890560989306495
|
||
|
|
* math.log(math.expm1(2) + 1) // returns number 2
|
||
|
|
*
|
||
|
|
* math.expm1([1, 2, 3])
|
||
|
|
* // returns Array [
|
||
|
|
* // 1.718281828459045,
