2 int - return the integer part of a number or of numbers in a value
8 If x is an object of type xx, int(x) requires xx_int to have been
9 defined; other conditions on x and the value returned depend on
10 the definition of xx_int.
14 x number (real or complex), matrix
16 return number or matrix
19 If x is an integer, int(x) returns x. For other real values of x,
20 int(x) returns the value of i for which x = i + f, where i is an
21 integer, sgn(f) = sgn(x) and abs(f) < 1.
23 If x is complex, int(x) returns int(re(x)) + int(im(x))*1i.
25 If x is a matrix, int(x) returns the matrix m with the same structure
26 as x in which m[[i]] = int(x[[i]]).
