An array B divided by a matrix A solves the system of equations AX=B for X; that is, X = A
–1
B.
This operation uses 15-digit internal precision, providing a more precise result than the calculation
INV(A)*B. The matrix must be square, and must have the same number of columns as the array
has rows (or elements, if the array is a vector).
A binary integer divided by a real or binary number returns a binary integer that is the integral part
of the quotient. (The real number is converted to a binary integer before the division.) A divisor
of zero returns # 0.
When dividing two unit objects, the scalar parts and the unit parts are divided separately.

= (Equal)
Type: Function
Description: Equals Analytic Function: Returns an equation formed from the two arguments.
The equals sign equates two expressions such that the difference between them is zero.
In Symbolic Results mode, the result is an algebraic equation. In Numerical Results mode, the
result is the difference of the two arguments because = acts equivalent to –. This allows
expressions and equations to be used interchangeably as arguments for symbolic and numerical
rootfinders.
