Python – cmath.inf 常量

cMath 模块包含许多用于复数数学运算的函数。 cmath.inf常量用于获得浮点正无穷大。

下面的例子说明了上述函数的使用:

示例 #1:

Python3
# Python code to implement
# the cmath.inf constant
        
# importing "cmath"
# for mathematical operations  
import cmath 
    
# Print the positive infinity
val = cmath.inf 
print(val)


Python3
# Python code to implement
# the cmath.inf constant
        
# importing "cmath"
# for mathematical operations  
import cmath 
    
# Print the negative infinity
val = -cmath.inf
print(val)


输出:

inf

示例 2:

Python3

# Python code to implement
# the cmath.inf constant
        
# importing "cmath"
# for mathematical operations  
import cmath 
    
# Print the negative infinity
val = -cmath.inf
print(val)

输出:

-inf
