Log1p

Returns the closest double approximation of the natural logarithm of the sum of the argument and 1.

Syntax

[Android.Runtime.Register("log1p", "(D)D", "")]
public static double Log1p (double d)

Parameters

d
the value to compute the ln(1+d) of.

Returns

Documentation for this section has not yet been entered.

Remarks

Returns the closest double approximation of the natural logarithm of the sum of the argument and 1. If the argument is very close to 0, it is much more accurate to use log1p(d) than log(1.0+d) (due to numerical cancellation). The returned result is within 1 ulp (unit in the last place) of the real result and is semi-monotonic.

Special cases:

log1p(+0.0) = +0.0
log1p(-0.0) = -0.0
log1p((anything
log1p(-1.0) = -infinity
log1p(+infinity) = +infinity
log1p(-infinity) = NaN
log1p(NaN) = NaN
