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.


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