Public Shared Function Log1PlusX ( _

static DoubleComplex Log1PlusX(
static member Log1PlusX :
z:DoubleComplex -> DoubleComplex
For small values of z,
the logarithm of 1 + z is close to
zero. When the logarithm is evaluated directly, this
can cause significant round-off error. This function
resolves this problem by using a direct approximation
for z close to 1.
