isInf function

Input type Output type
float bool

This function returns true if its argument is the special infinity floating-point value INF. Together with isNaN, you can use isInf to check if a floating-point value is still normal, which indicates that all previous operations on it were successful.

Examples:

float x = 1
print(x)         ; Prints 1
print(isInf(x))  ; Prints false
x = x / 0
print(x)         ; Prints INF
print(isInf(x))  ; Prints true
