Returns the value of the logarithm of one plus argument which is defined by `y == log(1 + x)` .
x, y
See the possible types for a unary standard math function.
CPPAD_USE_CPLUSPLUS_2011
true
If this preprocessor symbol is true (`1`), and `x` is an AD type, this is an atomic operation .
false
If this preprocessor symbol is false (`0`), CppAD uses the representation log 1 p ( x ) = log ( 1 + x ) to compute this function.
Example
The file log1p.cpp contains an example and test of this function. It returns true if it succeeds and false otherwise.
