Export assignment sincospi

• sincospi(out: Collection, x: number): Collection
• sincospi(x: number): Collection

• Simultaneously computes the sine and cosine of a number times π.

  Parameters

  • out: Collection

    destination array

  • x: number

    input value

  Returns Collection

  two-element array containing sin(πx) and cos(πx)

  Example

  var Float64Array = require( `@stdlib/array/float64` );
  
  var out = new Float64Array( 2 );
  
  var v = sincospi( out, 0.0 );
  // returns <Float64Array>[ 0.0, 1.0 ]
  
  var bool = ( v === out );
  // returns true

• Simultaneously computes the sine and cosine of a number times π.

  Parameters

  • x: number

    input value

  Returns Collection

  two-element array containing sin(πx) and cos(πx)

  Example

  var v = sincospi( 0.0 );
  // returns [ 0.0, 1.0 ]

  Example

  var v = sincospi( 0.5 );
  // returns [ 1.0, 0.0 ]

  Example

  var v = sincospi( 0.1 );
  // returns [ ~0.309, ~0.951 ]

  Example

  var v = sincospi( NaN );
  // returns [ NaN, NaN ]
