Description

log computes natural logarithm.

log2 computes a base 2 logarithm.

log10 computes a base 10 logarithm.

log1p computes log_e(1.0 + x).

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