What If 6A

The use of what if statements in coding is to help execute a code block if the conditions are true. The specified condition must be true in order for the execution of the code to be guaranteed. The basic syntax if/else statements are only executed if the condition of the code is true as well. Therefore these functions help to identify whether or no a block of code is true on the platform. The purpose of the ISNan function is to help verify the accuracy of a number being used in a function. The IsNan function typically returns as true if all else is false. The && used is evaluated when it is read from left to right. Typically it is returned right away with the original operator encountered. If and else functions are differentiated by what the overall results they intend on getting are. Therefore when it comes to if functions, it helps to bring out a code which when run, the condition must be proven as true versus the else function which expects the running of the code to be proven as false. Therefore they are differentiated by the  results that they correspond with which are true and false statements. The else statement does not take on a boolean expression but the IF statement does when the value is proven to be true.
