Ruby - Math.frexp() Method
The Ruby Math.frexp() method is used to break the number x into its binary significand (a floating point with an absolute value in range [0.5, 1.0)) and an integral exponent for 2. Mathematically, it can be expressed as:
x = significand * 2exponent
The method Returns a two-element array containing the significand (a Float) and exponent (an Integer) of x. If x is zero, both significand and exponent are zero. If x is negative, the significand returned by the function is negative.
Syntax
Math.frexp(x)
Parameters
x |
Specify the value to be decomposed. |
Return Value
Returns a two-element array containing the significand (a Float) and exponent (an Integer) of x.
Example:
The example below shows the usage of Math.frexp() method.
Num = 10
#decompose the number
sig, exp = Math.frexp(Num)
puts "Number: #{Num}"
puts "Significand: #{sig}"
puts "Exponent: #{exp}"
The output of the above code will be:
Number: 10 Significand: 0.625 Exponent: 4
