| 13 | * Calculate the value of subtracting 1 from the exponential value.
|
| 14 | * For matrices, the function is evaluated element wise.
|
| 15 | *
|
| 16 | * Syntax:
|
| 17 | *
|
| 18 | * math.expm1(x)
|
| 19 | *
|
| 20 | * Examples:
|
| 21 | *
|
| 22 | * math.expm1(2) // returns number 6.38905609893065
|
| 23 | * math.pow(math.e, 2) - 1 // returns number 6.3890560989306495
|
| 24 | * math.log(math.expm1(2) + 1) // returns number 2
|
| 25 | *
|
| 26 | * math.expm1([1, 2, 3])
|
| 27 | * // returns Array [
|
| 28 | * // 1.718281828459045,
|
| 29 | * // 6.3890560989306495,
