Arguments and Return Values Arguments: One (a 1x1x1 numeric array) integer or half-integer between 0 and 13; factorial is defined for half-integers such that fact(1/2) = ½√π Return Value: The factorial of the input (a 1x1x1 array; int for integer input, float for half-integer input) If no arguments are input, fact() prints its description, as shown below. Usage Syntax: fact(x) 'x' - a 1x1x1 array whose value is an integer or half-integer x, such that 0 ≤ x < 13 Examples dv> fact() Factorial fact(n), integer or half-integer 0 <= n < 13 Does NOT work for arrays, only for 1x1x1 inputs S.Marshall 12-06-2007 0 dv> fact(0) 1 dv> fact(0.5) 0.886227 dv> fact(1) 1 dv> fact(6) 720 dv> fact(12) 479001600 dv> fact(12.5) 1.71054e+09 dv> fact(13) Input must be integer or half-integer 0 <= n < 13 0
