红宝石 |浮点类 * 值

Float#*() : *()是 Ruby 中的 Float 类方法,它返回两个 Float 值的乘法值。

Syntax:  Float.*()

Parameter:  Float values - two operands

Return:  Multiplicative value of Float values

代码 #1:*() 方法示例

Ruby
# 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
 
# Multiplicative value of Float values
puts "Float a * b : #{a*b}\n\n"
 
puts "Float b * c : #{b*c}\n\n"
 
puts "Float a * c : #{c*a}\n\n"


Ruby
# Ruby code for Float.*() method
 
# declaring float value
a = -56.23333333
 
# declaring float value
b = 10000.0
 
# declaring float value
c = -(22 + 7.1)
 
# Multiplicative value of Float values
puts "Float a * b : #{a*b}\n\n"
 
puts "Float b * c : #{b*c}\n\n"
 
puts "Float a * c : #{c*a}\n\n"


输出 :

Float a * b : 22220000.0

Float b * c : 23280000.0

Float a * c : 12932.04

代码 #2:*() 方法的示例

# declaring float value
b = 10000.0
 
# declaring float value
c = -(22 + 7.1)
 
# Multiplicative value of Float values
puts "Float a * b : #{a*b}\n\n"
 
puts "Float b * c : #{b*c}\n\n"
 
puts "Float a * c : #{c*a}\n\n"

输出 :

Float a * b : -562333.3333

Float b * c : -291000.0

Float a * c : 1636.389999903
