🛐Math

Provides basic constants and mathematical functions.

Methods

math.abs()

Returns the absolute, or non-negative value, of a given value.

math.abs(-100)

// expected value: 100

math.cos()

Returns the cosine of the radian argument.

math.cos(math.pi / 2).round()

// expected value: 0

math.isNegative()

Determines if the specified value is negative.

math.isNegative(-100)

// expected value: true

math.isPositive()

Determines if the specified value is positive.

math.isPositive(100)

// expected value: true

math.isZero()

Determines if the specified value is zero.

math.isZero(5)

// expected value: false

math.sin()

Returns the sine of the radian argument.

math.sin(math.pi).round()

// expected value: 0

math.tan()

Returns the tangent of the radian argument.

math.tan(0).round()

// expected value: 0
