math.frexp() function

The math.frexp() function breaks f into a normalized fraction and an integral power of two. It returns frac and exp satisfying f == frac × 2**exp, with the absolute value of frac in the interval [½, 1).

*Output data type: Record*

  1. import "math"
  3. math.frexp(f: 22.0)
  5. // Returns {frac: 0.6875, exp: 5}

Parameters

f

The value used in the operation.

*Data type: Float*

Special cases

  1. math.frexp(f: ±0)   // Returns {frac: ±0, exp: 0}
  2. math.frexp(f: ±Inf) // Returns {frac: ±Inf, exp: 0}
  3. math.frexp(f: NaN)  // Returns {frac: NaN, exp: 0}
