红宝石 | BigDecimal sin()函数

BigDecimal#sin() : sin()是一个 BigDecimal 类方法,它将十进制的正弦返回到指定的精度位数,数字。

示例 #1:

# Ruby code for BigDecimal.sin() method
  
# loading library
require 'bigdecimal'
  
# declaring bigdecimal
a = BigDecimal("10")
  
# declaring bigdecimal
b = BigDecimal("1000") *2
  
# declaring bigdecimal
c = BigDecimal("11.43")
  
# sin() method
puts "BigDecimal a sin method : #{Math.sin(a)}\n\n"
  
puts "BigDecimal b sin method : #{Math.sin(b)}\n\n"
  
puts "BigDecimal a sin method : #{Math.sin(c)}\n\n"

输出 :

BigDecimal a sin method : -0.5440211108893698

BigDecimal b sin method : 0.930039504416137

BigDecimal a sin method : -0.9071119034933154

示例 #2:

# Ruby code for BigDecimal.sin() method
  
# loading library
require 'bigdecimal'
  
# declaring bigdecimal
a = BigDecimal('12')*12
  
# declaring bigdecimal
b = BigDecimal('10')+(22 ** 7.1) ** 10
  
# declaring bigdecimal
c = -BigDecimal('-3')
  
# sin() method
puts "BigDecimal a sin method : #{Math.sin(a)}\n\n"
  
puts "BigDecimal b sin method : #{Math.sin(b)}\n\n"
  
puts "BigDecimal a sin method : #{Math.sin(c)}\n\n"

输出 :

BigDecimal a sin method : -0.49102159389846933

BigDecimal b sin method : 0.9772308602356717

BigDecimal a sin method : 0.1411200080598672
