i've been toying around t-sql in attempt understand implicit conversion , overload resolution rules, somehow seems work bit strange... context: data type conversion: https://msdn.microsoft.com/en-us/library/ms191530.aspx data type precedence: https://msdn.microsoft.com/en-us/library/ms190309.aspx abs: https://msdn.microsoft.com/en-us/library/ms189800.aspx basically latter tells abs work on int, float, decimal, etc. let's see how works: declare @foo2 sql_variant; set @foo2 = abs(4); select sql_variant_property(@foo2, 'basetype') -- result: int. ok, apparently have int overload. expected. declare @foo2 sql_variant; set @foo2 = abs(cast(4.0 float)); select sql_variant_property(@foo2, 'basetype') -- result: float. ok, apparently have float overload. expected. now, according implicit type conversion table, allowed implicitly convert stuff. we're going check converting varbinary int, should happen according type precedence rules: declare @f...

i'm making extend scripts adobe illustrator cs6 (javascript) , need delete every clipping masks of document. i have solution it's not fast enough in big documents. here code: var releaseclippingmasks = function(document) { var pathitems = document.pathitems; log('looking clipping masks among ' + pathitems.length + ' elements'); var n = 0; for(var p = pathitems.length - 1; p >= 0; p--) { if(p / 1000 == math.round(p / 1000)) { log(p + ' remaining'); } if(pathitems[p].clipping) { // accessing element [p] of pathitems takes lot of time pathitems[p].remove(); n++; } } log(n + ' deleted masks'); } there not many clipping masks in documents, lot of pathitems (100000+), iterating takes long time. does know better way select every clipping masks in document javascript? appreciated. the fastest way select clipping mask , delete it: // select->objects->clipping mask app....

i have buffer unsigned char table[512] want convert faster table of short int table[256] every position compound bytes of table. i have camera give me buffer table convert disparity real depth. unsigned char zdtable[512] = {0}; unsigned short int zdtablehexa[256]={0}; .. buffer data..... (int = 0; < 256; ++i) { zdtablehexa[i]=zdtable[i*2]<<8 + zdtable[i*2+1]; } these 2 has problem in converting values, bytes inversed: memcpy(zdtablehexa_ptr,zdtable,256*sizeof( unsigned short int)); unsigned short* zdtablehexa = (unsigned short*)zdtable; try short* zdtablehexa = (short*)zdtable; it maps memory space of char array array of shorts. if memory looks this: (char0),(char1),(char2),(char3) then reinterpreted be (short0 = char0,char1),(short1 = char2,char3) beware such direct reinterpretation depends on endianness , formally allows sufficiently pedantic compiler ungood things, i.e., it's system- , compiler-specific.
