The Abs function takes a number and returns its absolute value.
The Exp function takes a numeric value and returns e (the base of natural logarithms) raised to a power.
The Hex function returns a string value containing the value of an arguement converted to hexadecimal format. If the arguement is a fractional value, it is rounded to the nearest whole number before the function returns the string.
The Int function returns the whole number portion of a numeric arguement. If the arguement is a negative value, it returns the first integer value that is less than or equal to the arguement.
The Fix function returns the whole number portion of a numeric arguement. If the arguement is a negative value, it returns the first integer value that is greater than or equal to the arguement.
The Rnd function returns a random number. Switch indicates how the random number will be determined. If switch is a positive number, the next random number in the sequence should be returned. Before calling this function, you should initialize it by using the Randomize statement.
The Sgn function returns a numeric vale representing the sign of a number arguement. It returns 1 if the numeric value is > 0, 0 if = 0, and -1 if < 0.
