vvlogbf(_:_:_:)
Calculates the unbiased exponent of each element in an array of single-precision values.
Declaration
func vvlogbf(_: UnsafeMutablePointer<Float>, _: UnsafePointer<Float>, _: UnsafePointer<Int32>)Discussion
Parameters:
- parameter 1
The output array, y.
- parameter 2
The input array, x.
- parameter 3
The number of elements in the arrays.
For a nonzero finite floating-point number f, logb is defined to be the integer that satisfies abs(f) = significand * 2**logb(f), with significand in [1,2).
If x is +/-0, y is set to -inf.
If x is +/-inf, y is set to +inf.
If x is NaN, y is set to NaN.
