t*d 发帖数: 1290	1 a = log(bcdef) AND a = log(a) + log(b) + log(c) + log(f) Which code is faster? Thx!
a**a 发帖数: 416	2 The former is faster, but the other is more stable from overflow. 【在 td 的大作中提到】 : a = log(bcde*f) : AND : a = log(a) + log(b) + log(c) + log(f) : Which code is faster? : Thx!
a******e 发帖数: 95	3 Modern compilers will consider them the same. 【在 td 的大作中提到】 : a = log(bcde*f) : AND : a = log(a) + log(b) + log(c) + log(f) : Which code is faster? : Thx!
