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

Export assignment exponentf

• exponentf(x: number): number

• Returns an integer corresponding to the unbiased exponent of a single-precision floating-point number.

  Parameters

  • x: number

    single-precision floating-point number

  Returns number

  unbiased exponent

  Example

  var toFloat32 = require( `@stdlib/number/float64/base/to-float32` );
  var exp = exponentf( toFloat32( 3.14e34 ) ); // => 2**114 ~ 2.08e34
  // returns 114

  Example

  var toFloat32 = require( `@stdlib/number/float64/base/to-float32` );
  var exp = exponentf( toFloat32( 3.14e-34 ) ); // => 2**-112 ~ 1.93e-34
  // returns -112

  Example

  var toFloat32 = require( `@stdlib/number/float64/base/to-float32` );
  var exp = exponentf( toFloat32( -3.14 ) );
  // returns 1

  Example

  var exp = exponentf( 0.0 );
  // returns -127

  Example

  var exp = exponentf( NaN );
  // returns 128
