Ruby | Math frexp() function

The frexp() function in Ruby returns a two-element array containing the normalized fraction which is a float value and an exponent that is an integer value of the given number. On equating, fraction ** (2 ^ exponent) gives back the number.

Syntax: Math.frexp(number)

Parameter: The function takes a mandatory parameter number whose normalised fraction and exponent are to be returned.

Return Value: The function returns a two-element array.

Example 1:

# Ruby program for frexp() function

# Assigning values
val1 = 123
val2 = 256
val3 = 23
val4 = 18

# Prints the frexp() value
puts Math.frexp(val1)
puts
puts Math.frexp(val2)
puts
puts Math.frexp(val3)
puts
puts Math.frexp(val4)

Output:

Example 2:

# Ruby program for frexp() function

# Assigning values
val1 = 3213
val2 = 12
val3 = 16
val4 = 23

# Prints the frexp() value
puts Math.frexp(val1)
puts
puts Math.frexp(val2)
puts
puts Math.frexp(val3)
puts
puts Math.frexp(val4)
