Ganesh Ajjanagadde	db1a642cd2	all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.h The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S.

Mans Rullgard	f0c07be649	celp_math: rename ff_log2 to ff_log2_q15 This name is more descriptive as the function returns a fixed-point value with 15 fraction bits. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
