Miscellaneous functions are a selection of additional mathematical functions.
You can access them in the Formula Contents dialog box and in the Rule Contents dialog box. Select functions from the Math list in the Operators area of the dialog box.
fabs
This function calculates the absolute value of a number.
Parameter: number
The following formula calculates the local center of gravity from the start point with fabs giving the absolute number. For example, the absolute value of -3.54 is 3.54.
exp
This function calculates the involution of e, to a specified power. e is Euler’s number.
Parameter: power
The following formula calculates the involution of e to the power of two, which equals 7.389056 in a report.
ln
This function returns the natural logarithm of the parameter (base number e).
Parameter: number
The following formula calculates the natural logarithm of 5, which prints 1,60944 in a report.
log
This function returns the logarithm of the parameter (base number 10)
Parameter: number
The following formula calculates the logarithm of the number in the brackets. The report prints the final calculation of 0,698970. The length of the printed number (with decimals) is determined in the Value Field Properties dialog box in the Length field.
sqrt
This function calculates the square root of a number.
Parameter: number
The following formula acts as a filter to calculate the distance between the start and end points, where sqrt calculates the square root and pow calculates the involution.
mod
This function calculates modulo, the remainder after division.
Parameters: dividend, divider
The following formula calculates modulo and prints 3 in a report.
pow
This function calculates the involution of a value.
Parameters: base number, power
This formula calculates the distance between the start and end points, where sqrt calculates the square root and pow calculates the involution.
hypot
This function calculates the hypotenuse of a triangle.
Parameters: side, side
The following formula calculates the hypotenuse and prints 5 in a report.
n!
This function calculates the factorial of a number.
Parameter: number
The following formula calculates the factorial of 4. This translates to 4x3x2x1 and a report would display the result, 24.
round
This function rounds off a number according to given accuracy.
Parameters: number, accuracy
This formula rounds the number to two decimals, which is specified in the formula (0.01). The report prints 13.65.
and
This is a binary operation (and similar to & in the C language).
Parameters: parameter 1, parameter 2
The following example prints 1 in the report.
or
This is a binary operation (and similar to | in the C language).
Parameters: parameter 1, parameter 2
The following example prints 7 in the report.
