kotlin-stdlib / kotlin.math / ln1p
Platform and version requirements: JVM (1.2), JS (1.2), Native (1.2) 
fun ln1p(x: Double): Double

Computes ln(x + 1).

This function can be implemented to produce more precise result for x near zero.

Special cases:

  • ln1p(NaN) is NaN
  • ln1p(x) is NaN where x < -1.0
  • ln1p(-1.0) is -Inf
  • ln1p(+Inf) is +Inf
