C++ Math isinf()
The function determines whether the number is infinite or not. It can be positive or negative infinite. If the number is infinite, it returns 1 otherwise 0.
Suppose a number is 'x'. Syntax would be:
x: It is a floating point value.
Let's see the simple example when the value of x is 1.0/0.0.
value of x is : inf isinf(x) : 1
In this example, isinf() function determines that the value of x is infinite. Therefore, it returns 1.
Let's see the simple example when the value of x is 4.
value of x is : 4 isinf(x) : 0
In this example, isinf() function determines that the value of x is finite. Therefore, it returns 0 value.
