Math rule functions
This topic describes the available math rule functions.
ABS
Returns the absolute value of a number.
Syntax
ABS(Value)
Where Value is a number, or a formula that returns a number.
Example
ABS(-2.1) returns "2.1"
ABS(5.4) returns "5.4"
ACOS
Returns an angle in radians, whose cosine is a specified value.
Syntax
ACOS(Value)
Where Value is a number between -1 and 1 or a formula which returns a value between -1 and 1. If Value is outside of these bounds, the result is undefined.
Example
ACOS(0) returns "1.5708" radians (pi/2 or 90 degrees)
ACOS(1) returns "0"
ASIN
Displays an angle in radians, whose sine is a specified value.
Syntax
ASIN(Value)
Where Value is a number between -1 and 1, or a formula which returns a value between -1 and 1. If Value is outside of these bounds, the result is undefined.
Example
ASIN(1) returns "1.5708" radians (pi/2 or 90 degrees)
ASIN(0) returns "0"
ATAN
Returns an angle in radians, with a tangent of a specifed angle. The result is between -pi/2 and +pi/2.
Syntax
ATAN(Value)
Where Value is a number or a formula that returns a number.
Example
ATAN(1) returns "0.7854" radians (pi/4 or 45 degrees)
ATAN(0) returns "0" radians
COS
Returns the cosine of an angle.
Syntax
COS(Value)
Where Value is an angle in radians, or a formula which returns and angle in radians.
Example
COS(0) returns "1"
COS(1.5708) returns "0"
EXP
Returns the natural anti-logarithm of a value.
Syntax
EXP(Value)
Where Value is a number.
Examples
EXP(0) returns "1"
EXP(1) returns "2.71828182845905"
INT
Returns the integer resulting from truncating a number.
Syntax
INT(Value)
Where Value is a number or a formula resulting in a number. If Value is positive, the result is the largest integer less than or equal to Value. If Value is negative, the result is the smallest integer greater than or equal to Value.
Examples
INT(7.8) returns "7"
INT(-7.8) returns "-7"
ISNULL
Determines whether a cell is empty
Syntax
ISNULL(cube, Elem1, Elem2 ...)
Cube is the name of the cube; Elem1, Elem2... are the cells in this cube.
LN
Returns the natural (base) logarithm of a value.
Syntax
LN(Value)
Where Value is any positive number. If Value is negative or zero, the result is undefined.
Examples
LN(1) returns "0"
LN(2.71828) returns "1"
LOG
Returns the logarithm (base 10) of a number.
Syntax
LOG(Value)
Value is any positive number. If Value is negative or zero, the result is undefined.
Examples
LOG(1) returns "0"
LOG(10) returns "1"
Syntax
MAX(Value1, Value2)
Where both arguments are numbers, or formulas which return numbers.
Example
MAX(100, 10) returns "100"
MIN
Returns the smaller of two values.
Syntax
MIN(Value1, Value2)
Where both arguments are numbers, or formulas which return numbers.
Example
MIN(100, 10) returns "10"
MOD
Returns the remainder resulting from dividing one number by another.
Syntax
MOD(Value1, Value2)
Where both arguments are numbers, or formulas which return numbers.
Examples
MOD(100, 10) returns "0"
MOD(102,10) returns "2"
PI
Returns 3.1415927.
Syntax
PI
This function has no arguments.
ROUND
Return a value rounded to the nearest integer.
Syntax
Round(Value)
Value must be a number, or a formula that returns a number.
Examples
ROUND(3.4) returns 3.
ROUND(3.5) returns 4.
ROUNDP
Returns a value representing a number rounded to the nearest of a specifed number of digits.
Syntax
ROUNDP(Value, Decimals)
Where Value is the number to be rounded and Decimals is the number of decimals to which the number should be rounded. If Decimals is negative then the number will be rounded to digits to the left of the decimal separator.
Examples
ROUNDP(1.234,1) returns "1.2"
ROUNDP(2035,-1) returns "2040"
ROUNDP(1.235,2) returns "1.24"
SIGN
Determines whether a number is positive.
Syntax
SIGN(Value)
Value is a number, or a formula that returns a number. The function returns 1 if Value is positive, -1 if Value is negative and 0 if Value is 0.
Example
SIGN(-3.4) returns "-1"
SIN
Returns the sine of a number entered in radians.
Syntax
SIN(Value)
Examples
SIN(0) returns 0.
SIN(1.5708) returns 1.
SQRT
Returns the square root of a value.
Syntax
SQRT(Value)
Value is a number, or a formula that returns a number. If Value is negative, the result is undefined.
Example
SQRT(9) returns 3.
TAN
Returns the tangent of a value entered in radians.
Syntax
TAN(Value)
Example
TAN(0) returns 0.
TAN(.7854) returns 1.
