4.5.2 intvec expressions
An intvec expression is:
-
a range: int expression
..int expression - a function returning intvec
-
intvec operations with int (
+,-,*,/,%) -
intvec operations (
+,-) -
intvec operation with intmat (
*) - a type cast to intvec
Example:
intvec v=-1,2; intvec w=v,v; // concatenation w; → -1,2,-1,2 w = -2..2,v,1; w; → -2,-1,0,1,2,-1,2,1 intmat m[3][2] = 0,1,2,-2,3,1; m*v; → 2,-6,-1 typeof(_); → intvec v = intvec(m); v; → 0,1,2,-2,3,1 ring r; poly f = x2z + 2xy-z; f; → x2z+2xy-z v = leadexp(f); v; → 2,0,1 |
