Functions ​

math.abs(val: Int) -> Int ​

Get the absolute value of an integer.

nbcl
math.abs(-10) # result: 10

math.sqrt(val: Float) -> Float ​

Get the square root of a floating number.

nbcl
math.sqrt(36.0) # result: 6.0

math.cbrt(val: Float) -> Float ​

Get the cube root of a floating number.

nbcl
math.cbrt(27.0) # result: 3.0

math.pow(base: Float, exp: Float) -> Float ​

Get the 'x' power of a floating number.

nbcl
math.pow(3.0, 3.0) # result: 27.0

math.floor(val: Float) -> Float ​

Returns the largest integer less than or equal to a floating number.

nbcl
math.floor(3.9) # result: 3.0

math.ceil(val: Float) -> Float ​

Returns the smallest integer greater than or equal to a floating number.

nbcl
math.ceil(3.1) # result: 4.0

math.round(val: Float) -> Float ​

Returns the nearest integer to a floating number. Rounds half-way cases away from zero.

nbcl
math.round(3.5) # result: 4.0

math.trunc(val: Float) -> Float ​

Returns the integer part of a floating number, removing any fractional digits.

nbcl
math.trunc(3.9) # result: 3.0

math.sin(val: Float) -> Float ​

Computes the sine of a floating number (in radians).

nbcl
math.sin(0.0) # result: 0.0

math.cos(val: Float) -> Float ​

Computes the cosine of a floating number (in radians).

nbcl
math.cos(0.0) # result: 1.0

math.tan(val: Float) -> Float ​

Computes the tangent of a floating number (in radians).

nbcl
math.tan(0.0) # result: 0.0

math.asin(val: Float) -> Float ​

Computes the arcsine of a floating number, returning a value in radians.

nbcl
math.asin(0.0) # result: 0.0

math.atan2(y: Float, x: Float) -> Float ​

Computes the four-quadrant arctangent of y and x in radians.

nbcl
math.atan2(1.0, 0.0)
