Example

Calculates the negative of the sines of the elements in a vector, where the elements are angles measured in degrees. Since the C library function sin takes its arguments in radians, this operation is the composition of three operations: negation, sin, and the conversion of degrees to radians.

vector angles;

vector sines;

const double pi = 3.14159265358979323846;

assert(sines.size() >= angles.size());

transform(angles.begin(), angles.end(), sines.begin(), compose1(negate(), compose1(ptr_fun(sin), bind2nd(multiplies(), pi / 180.))));
