math.atan2(3, -3) / math.pi;      // 0.75
math.log(1000, 10);               // 3
math.sqrt(-4);                    // 2i
math.pow([[-1, 2], [3, 1]], 2);   // [[7, 0], [0, 7]]

// Expressions
math.eval('12 / (2.3 + 0.7)');    // 4
math.eval('5.08 cm to inch');     // 2 inch
math.eval('sin(45 deg) ^ 2');     // 0.5
math.eval('9 / 3 + 2i');          // 3 + 2i
math.eval('det([-1, 2; 3, 1])');  // -7

// Chained operations
math.select(3)
    .add(4)
    .multiply(2)
