No, it differs in the handling of signaling NaNs (with minimumNumber, if the NaN argument is signaling, it results in the "invalid" exception but the non-NaN argument is still returned, whereas with minNum, a quiet NaN was returned in that case). A new fminimum_num function is proposed as a C binding to the new operation. http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2273.pdf (The new operations are also more strictly defined regarding zero arguments, to treat -0 as less than +0, which was unspecified for minNum and fmin.) -- Joseph S.
