Description | VF_cosectab2[ i ] = cosec ( i/(2*VF_tabsz2) * p ), i=0,...,VF_tabsz2−1
VF_cosectab3[ i ] = cosec ( i/(2*VF_tabsz3) * p ), i=0,...,VF_tabsz3−1
VF_cosectab2[ VF_tabsz2 ] = VF_cosectab3[ VF_tabsz3 ] = 0
These look-up tables of cosecant values for arguments between 0 and p/2 are used by VF_cosecrpi2 and the other functions of that family and are also available to the user. Since the cosecant of p/2 is not defined, zero is stored at its place.
C/C++: The symbols VF_tabsz2 etc., denoting the size of the tables, are defined in <xmath.h>.
Pascal/Delphi: The symbols VF_tabsz2 etc. are defined in the same units as the tables themselves.
FreePascal/Lazarus: These tables are not available for FreePascal/Lazarus. |
