kotlin-stdlib / kotlin.math / ln1p ln1p Common JVM JS 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 See Also ln expm1 Common JVM JS Native 1.2 fun ln1p(x: Float): Float Computes ln(a + 1).
