External module "number/float32/base/normalize/docs/types/index.d"

Export assignment normalizef

• normalizef(out: ArrayLike<number>, x: number): ArrayLike<number>
• normalizef(x: number): ArrayLike<number>

• Returns a normal number y and exponent exp satisfying \(x = y \cdot 2^\mathrm{exp}\).

  Parameters

  • out: ArrayLike<number>

    output array

  • x: number

    single-precision floating-point number

  Returns ArrayLike < number >

  output array

  Example

  var Float32Array = require( `@stdlib/array/float32` );
  var toFloat32 = require( `@stdlib/number/float64/base/to-float32` );
  
  var out = new Float32Array( 2 );
  
  var v = normalizef( out, toFloat32( 1.401e-45 ) );
  // returns <Float32Array>[ 1.1754943508222875e-38, -23 ]
  
  var bool = ( v === out );
  // returns true

• Returns a normal number y and exponent exp satisfying \(x = y \cdot 2^\mathrm{exp}\).

  Parameters

  • x: number

    single-precision floating-point number

  Returns ArrayLike < number >

  output array

  Example

  var toFloat32 = require( `@stdlib/number/float64/base/to-float32` );
  
  var v = normalizef( toFloat32( 1.401e-45 ) );
  // returns [ 1.1754943508222875e-38, -23 ]

  Example

  var v = normalizef( 0.0 );
  // returns [ 0.0, 0 ]

  Example

  var PINF = require( `@stdlib/constants/float32/pinf` );
  
  var v = normalizef( PINF );
  // returns [ +Infinity, 0 ]

  Example

  var NINF = require( `@stdlib/constants/float32/ninf` );
  
  var v = normalizef( NINF );
  // returns [ -Infinity, 0 ]

  Example

  var v = normalizef( NaN );
  // returns [ NaN, 0 ]
