|
15 | * Round a value towards minus infinity.
|
16 | * For matrices, the function is evaluated element wise.
|
17 | *
|
18 | * Syntax:
|
19 | *
|
20 | * math.floor(x)
|
21 | *
|
22 | * Examples:
|
23 | *
|
24 | * math.floor(3.2) // returns number 3
|
25 | * math.floor(3.8) // returns number 3
|
26 | * math.floor(-4.2) // returns number -5
|
27 | * math.floor(-4.7) // returns number -5
|
28 | *
|
29 | * const c = math.complex(3.2, -2.7)
|
30 | * math.floor(c) // returns Complex 3 - 3i
|
31 | *
|
32 | * math.floor([3.2, 3.8, -4.7]) // returns Array [3, 3, -5]
|
33 | *
|
34 | * See also:
|
35 | *
|
36 | * ceil, fix, round
|
37 | *
|
38 | * @param {number | BigNumber | Fraction | Complex | Array | Matrix} x Number to be rounded
|
39 | * @return {number | BigNumber | Fraction | Complex | Array | Matrix} Rounded value
