红宝石 |浮点类**值
Float#**() : **()是 Ruby 中的 Float 类方法,它返回引发的幂的值。
Syntax: Float.a**n()
Parameter: Float values - two operands a, n
Return: a to the power of n, an
代码 #1:**() 方法的示例
# Ruby code for Float.**() method
# declaring float value
a = -100.7 - 10.4
# declaring float value
b = -100 * 2000.0
# declaring float value
c = -(22 + 7.1) * 4
# a
puts "Float a ** b : #{a**b}\n\n"
# b
puts "Float b ** c : #{b**c}\n\n"
# c
puts "Float a ** c : #{c**a}\n\n"
输出 :
Float a ** b : 0.0
Float b ** c : 0.0+0.0i
Float a ** c : -2.8237758046030776e-230+9.175003766615921e-231i
代码 #2:**() 方法的示例
# Ruby code for Float.**() method
# declaring float value
a = -56.23333333
# declaring float value
b = 10000.0
# declaring float value
c = -(22 + 7.1)
# a
puts "Float a ** b : #{a**b}\n\n"
# b
puts "Float b ** c : #{b**c}\n\n"
# c
puts "Float a ** c : #{c**a}\n\n"
输出 :
Float a ** b : Infinity
Float b ** c : 3.9810717055349206e-117
Float a ** c : 3.5603365534761494e-83-3.2057413643006885e-83i
