The code creates a function to print the first 25 Vampire numbers and their fangs. Instance of this class as argument and returns the appropriate precedence The following Mathematica code yields a list of vampire numbers.
Then a function can be inserted in this dictionary that takes an Sometimes it’s not enough to assign a fixed precedence value to aĬlass. > from sympy.printing import print_ccode > from sympy.functions import sin, cos, Abs > from sympy.abc import x > print_ccode ( sin ( x ) ** 2 + cos ( x ) ** 2 ) pow(sin(x), 2) + pow(cos(x), 2) > print_ccode ( 2 * x + cos ( x ), assign_to = "result" ) result = 2*x + cos(x) > print_ccode ( Abs ( x ** 2 )) fabs(pow(x, 2)). Pprint is just a shortcut for this function.
