Examples

math.fix(3.2)                // returns number 3
math.fix(3.8)                // returns number 3
math.fix(-4.2)               // returns number -4
math.fix(-4.7)               // returns number -4

math.fix(3.12, 1)                // returns number 3.1
math.fix(3.18, 1)                // returns number 3.1
math.fix(-4.12, 1)               // returns number -4.1
math.fix(-4.17, 1)               // returns number -4.1

const c = math.complex(3.22, -2.78)
math.fix(c)                  // returns Complex 3 - 2i
math.fix(c, 1)               // returns Complex 3.2 - 2.7i

math.fix([3.2, 3.8, -4.7])      // returns Array [3, 3, -4]
