Function in prelude::math auto-imported

`sin`

fn sin(float x) -> float

Source: compiler/src/builtin_docs/prelude/math.hy

Returns the sine of x (in radians).

Like every scalar function in prelude::math, it takes and returns float and follows IEEE-754: invalid inputs give NaN and overflow gives infinity, never a clamped value. Auto-imported.

Parameters#

Name	Type
`x`	`float`

Returns#

float

Examples#

use tests::assert;
let pi = 3.141592653589793;
assert!(sin(0.0) == 0.0);
assert!(sin(pi / 2.0) == 1.0);
