Assuming (Built-in Mathematica Symbol)

Assuming[assum, expr] evaluates expr with assum appended to $Assumptions, so that assum is included in the default assumptions used by functions such as Refine, Simplify, and ...

Boole (Built-in Mathematica Symbol)

Boole[expr] yields 1 if expr is True and 0 if it is False.

ByteCount (Built-in Mathematica Symbol)

ByteCount[expr] gives the number of bytes used internally by Mathematica to store expr.

CarmichaelLambda (Built-in Mathematica Symbol)

CarmichaelLambda[n] gives the Carmichael function \[Lambda](n), defined as the smallest integer m such that k^m \[Congruent] 1 mod n for all k relatively prime to n.

CellMargins (Built-in Mathematica Symbol)

CellMargins is an option for Cell that specifies the absolute margins in printer's points to leave around a cell.

Erfi (Built-in Mathematica Symbol)

Erfi[z] gives the imaginary error function erf(i z)/i.
