+   * Round a value towards minus infinity.
+   * For matrices, the function is evaluated element wise.
+   *
+   * Syntax:
+   *
+   *    math.floor(x)
+   *    math.floor(x, n)
+   *
+   * Examples:
+   *
+   *    math.floor(3.2)              // returns number 3
+   *    math.floor(3.8)              // returns number 3
+   *    math.floor(-4.2)             // returns number -5
+   *    math.floor(-4.7)             // returns number -5
+   *
+   *    math.floor(3.212, 2)          // returns number 3.21
+   *    math.floor(3.288, 2)          // returns number 3.28
+   *    math.floor(-4.212, 2)         // returns number -4.22
+   *    math.floor(-4.782, 2)         // returns number -4.79
+   *
+   *    const c = math.complex(3.24, -2.71)
+   *    math.floor(c)                 // returns Complex 3 - 3i
+   *    math.floor(c, 1)              // returns Complex 3.2 -2.8i
+   *
+   *    math.floor([3.2, 3.8, -4.7])       // returns Array [3, 3, -5]
+   *    math.floor([3.21, 3.82, -4.71], 1)  // returns Array [3.2, 3.8, -4.8]
+   *
+   *    math.floor(math.tau, [2, 3])  // returns Array [6.28, 6.283]
+   *
+   *    // Note that floor(array, array) currently not implemented.
+   *
+   * See also:
+   *
+   *    ceil, fix, round
+   *
+   * @param  {number | BigNumber | Fraction | Complex | Array | Matrix} x  Number to be rounded
