4.2.6 Miscellaneous

- -

(use-modules (sly math))
-

- -

A grab bag of commonly used math functions and constants. -

Scheme Variable: pi: An approximation of \pi, the ratio of a circle’s circumference to its -diameter. -

- -

Scheme Variable: 2pi: 2\pi -

- -

Scheme Variable: pi/2: \pi/2 -

- -

Scheme Procedure: degrees->radians angle: Convert angle from degrees to radians. -

- -

Scheme Procedure: radians->degrees angle: Convert angle from radians to degrees. -

- -

Scheme Procedure: sin-degrees angle: Return the sine of angle, where angle is measured in -degrees. -

- -

Scheme Procedure: cos-degrees angle: Return the cosine of angle, where angle is measured in -degrees. -

- -

Scheme Procedure: tan-degrees angle: Return the tangent of angle, where angle is measured in -degrees. -

- -

Scheme Procedure: atan-degrees y x: Return the arctangent of y and x, where y and -x are measured in degrees. -

- -

Scheme Procedure: cotan z: Return the cotangent of z. -

- -

Scheme Procedure: clamp min max x: Restrict x to the range [min, max], assuming that -min is actually less than max. -

- -

Scheme Procedure: linear-scale min max a b n: Map n in the range [min, max] to the range [a, b]. -

- -

Scheme Procedure: half x: Return x / 2. -

- -

Scheme Procedure: square x: Return x^2. -

- -

Scheme Procedure: make-lerp + *: Return a new procedure that accepts three arguments: start, -end, and alpha. The returned procedure uses the -procedures + and * to linearly interpolate a value between -start and end. alpha should always be in the range -[0, 1]. -

- -

Scheme Procedure: lerp start end alpha: Return the linear interpolation between the numbers start and -end with scalar factor alpha. -

- -

Scheme Procedure: modulo* x y: Return the remainder of x / y. Works like regular -modulo, except that x and y may be rational numbers -or inexact numbers. -
