PrimeQ (Built-in Mathematica Symbol)

PrimeQ[expr] yields True if expr is a prime number, and yields False otherwise.

Exact and Approximate Results (Mathematica Tutorial)

A standard electronic calculator does all your calculations to a particular accuracy, say ten decimal digits. With Mathematica, however, you can often get exact results. ...

MLGetInteger16() (Mathematica MathLink C Function)

int MLGetInteger16 (MLINK link, short *i) gets a 16-bit integer from the MathLink connection specified by link and stores it as a C short in i.

MLGetInteger32() (Mathematica MathLink C Function)

int MLGetInteger32 (MLINK link, int *i) gets a 32-bit integer from the MathLink connection specified by link and stores it in i.

MLGetInteger64() (Mathematica MathLink C Function)

int MLGetInteger64 (MLINK link, mlint64 *i) gets a 64-bit integer from the MathLink connection specified by link and stores it in i.

MLGetInteger() (Mathematica MathLink C Function)

int MLGetInteger (MLINK link, int *i) gets an integer from the MathLink connection specified by link and stores it in i.

MLPutInteger32() (Mathematica MathLink C Function)

int MLPutInteger32 (MLINK link, int i) puts the 32-bit integer i to the MathLink connection specified by link.

Simplifying with Assumptions (Mathematica Tutorial)

Simplifying with assumptions. Mathematica does not automatically simplify this, since it is only true for some values of x. Sqrt[x^2] is equal to x for x≥0, but not otherwise.

MLPutInteger16() (Mathematica MathLink C Function)

int MLPutInteger16 (MLINK link, int i) puts the 16-bit integer i to the MathLink connection specified by link.

Modulus (Built-in Mathematica Symbol)

Modulus -> n is an option that can be given in certain algebraic functions to specify that integers should be treated modulo n.
