## FXND

CAS:
Split a fractional object into its numerator and denominator.

### GAMMA

Type:
Function
Description: Evaluate the function at the given point. For a positive integer x, (x) is equal to (x +1)!
GAMMA differs from the FACT and ! functions because it allows complex arguments. The
function is defined by
!´L
Access:
Input:
A real or complex number, x.
Output:
(x). If the input x is an integer greater than 100, returns the symbolic expression GAMMA(x).
Flags:
If the Underflow Exception (–20) or Overflow Exception (–21) flags are set then underflow or
overflow conditions give errors, otherwise they give zero or the maximum real number the calculator
can express.
Complex mode must be set (flag –103 set) if x is complex.
FACT, PSI, Psi, !

### GAUSS

CAS:
Return the diagonal representation of a quadratic form.

### GBASIS

CAS:
Return a set of polynomials that are a Grœbner basis G of the ideal I of an input set of
polynomials.

### GCD

CAS:
Return the greatest common divisor of two objects.

### GCDMOD

CAS:
Find the greatest common divisor of two polynomials modulo the current modulus.

### GET

Type:
Command
Description: Get Element Command: Returns from the argument 1/level 2 array or list (or named array or
list) the real or complex number z
