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
