ODD(num-to-round)  num-to-round: The number to be rounded. num-to-round is a number value. Usage Notes  To round to an even number, use the EVEN function. Examples =ODD(1) returns 1. =ODD(0) returns 1.

PI() Usage Notes  The PI function does not have any arguments. However, you must include the parentheses: =PI().  PI is accurate to 15 decimal places. Examples =PI() returns 3. 14159265358979. =SIN(PI()/2) returns 1, the sine of /2 radians or 90 degrees.

POWER(number, exponent)  number: A number.  exponent: The power to which to raise the given number. exponent is a number value. Usage Notes  The POWER function produces the same result as the ^ operator: =POWER(x, y) returns the same result as =x^y. 186 Chapter 8 Numeric Functions Examples =POWER(2, 3) returns 8. =POWER(100, 0. 5) returns 10.

PRODUCT(num-value, num-value. . . )  num-value: A number.  num-value. . . : Optionally include one or more additional numbers. Usage Notes  Empty cells included within the values are ignored and do not affect the result. Examples =PRODUCT(2, 4) returns 8. =PRODUCT(0. 5, 5, 4, 5) returns 50.

QUOTIENT(dividend, divisor)  dividend: A number to be divided by another number.  divisor: A number to divide into another number. If 0, a division by zero will result and the function will return an error. Usage Notes  If either, but not both, the dividend or divisor is negative, the result will be negative. If the sign of both the dividend and the divisor is the same, the result will be positive.  Only the whole part of the quotient is returned. The fractional part (or remainder) is ignored. Examples =QUOTIENT(5, 2) returns 2. [. . . ] Determines the total number of responses to the first question (9). By extending this formula across the row, you could determine the total number of responses to each question. Because all the data is numeric, COUNTA returns the same results. If, however, the survey had used A through E, instead of 1 through 5, you would need to use COUNTA to tally the results. [. . . ]
