math.expm1() function
math.expm1() returns e**x - 1, the base-e exponential of x minus 1.
It is more accurate than math.exp(x:x) - 1 when x is near zero.
Function type signature
(x: float) => float
For more information, see Function type signatures.
Parameters
x
(Required) Value to operate on.
Examples
Get more accurate base-e exponentials for values near zero
import "math"
math.expm1(x: 0.022)// 0.022243784470438233
Use math.expm1 in map
import "math"
data
|> map(fn: (r) => ({r with _value: math.expm1(x: r._value)}))
