Returns the natural logarithm of the magnitude of a complex number.

Numeric DatatypesmethodCComplex.incdocumented

Syntax

FUNCTION CLogAbs () AS DOUBLE

Description

Returns the natural logarithm of the magnitude of the complex number z, log|z|. It allows an accurate evaluation of \log|z| when |z| is close to one. The direct evaluation of log(CAbs(z)) would lead to a loss of precision in this case.

Example

DIM cpx AS CComplex = CComplex(1.1, 0.1) PRINT cpx.CLogAbs Output: 0.09942542937258279
