These functions can be accessed from the Math library from the Definition menu.

Abs(x): Returns the absolute value of x. When x in complex, returns the magnitude, see Complex number functions.

Abs(180) → 180

Abs(-210) → 210

Ceil(x): Returns the smallest integer that is greater than or equal to x.

Ceil(3.1) → 4

Ceil(5) → 5

Ceil(-2.9999) → -2

Ceil(-7) → -7

Ceil(x,digits): Returns the smallest number with the indicated of digits to the right of the decimal that is greater than or equal to x.

Ceil(Pi,4) → 3.1416

Ceil(-12345,-2) → -12300

Floor(x): Returns the largest integer that is smaller than or equal to x.

Floor(2.999) → 2

Floor(3) → 3

Floor(-2.01) → -3

Floor(-5) → -5
