Description

log computes natural logarithm.

       log2 computes a base 2 logarithm.

       log10 computes a base 10 logarithm.

       log1p computes loge(1.0 + x).

       logb computes the exponent of x, which is the integral part of logr |x|.

       half_log computes natural logarithm.

       half_log2 computes a base 2 logarithm.

       half_log10 computes a base 10 logarithm.

       native_log computes natural logarithm over an implementation-defined range. The maximum error is
       implementation-defined.

       native_log2 computes a base 2 logarithm over an implementation-defined range. The maximum error is
       implementation-defined.

       native_log10 computes a base 10 logarithm over an implementation-defined range. The maximum error is
       implementation-defined.
