红宝石 | CMath asin() 方法

asin() 方法是 CMath 类，用于返回给定值的反正弦值。

Syntax: Math.asin(z)

Parameter: Here, z is the value whose arc sine is to be calculated.

Returns: This method returns the arc sine value of the z.

示例 1：

# Ruby code for asin() method
require 'cmath'
  
# Initialize value 
a = 0.3584
b = 2
  
# Printing result  
puts "asin value of a : #{CMath.asin(a)}\n\n" 
puts "asin value of b : #{CMath.asin(b)}\n\n"

输出：

asin value of a : 0.3665534738291246

asin value of b : 1.5707963267948966-1.3169578969248166i

示例 2：

# Ruby code for asin() method
require 'cmath'
  
# Initialize value 
a = 0
b = -0.247
  
# Printing result  
puts "asin value of a : #{CMath.asin(a)}\n\n" 
puts "asin value of b : #{CMath.asin(b)}\n\n"

输出：

asin value of a : 0.0

asin value of b : -0.24958310188075922
