Formulas support standard arithmetic operations and trigonometric functions. Formulas support the following arithmetic operations: addition, subtraction, multiplication, division, exponentiation, logarithms, and square roots. Formulas also support the following trigonometric functions: sine, cosine, tangent, arcsine, arccosine, and arctangent. The valid formula abbreviations for arithmetic operations and trigonometric functions are Addition— + Subtraction— - Multiplication—* Division—/ Exponentiation—^: x^y, x raised to the power of y Logarithm—log Natural logarithm—ln Square root—sqrt: sqrt(16) Sine—sin Cosine—cos Tangent—tan Arcsine—asin Arccosine—acos Arctangent—atan e raised to an x power—exp(x) Absolute Value—abs Pi—pi (3.1415926...)You can enter integers, decimals, and fractional values in formulas, using normal mathematical syntax, as shown in the examples below: Length = Height + Width + sqrt(Height*Width) Length = Wall 1 (11000mm)+ Wall 2 (15000mm) Area = Length (500mm) * Width (300mm) Area = pi() * Radius ^ 2 Volume = Length (500mm) * Width (300mm) * Height (800 mm) Width = 100m * cos(angle) x = 2*abs(a) + abs(b/2) ArrayNum = Length/Spacing You can use the round function for values in formulas. Function syntax Description Examples round(x) The round function returns a value rounded to the nearest whole number. It doesn't take into consideration rounding direction.round(3.1) = 3 round(3.5) = 4 round(-3.7) = -4 roundup(x) The roundup function returns a value to the largest integral value greater than or equal to x.roundup(3) = 3 roundup(3.1) = 4 roundup(-3.7) = -3 rounddown(x) The rounddown function returns a value to the smallest integral value less than or equal to x.rounddown(3) = 3 rounddown(3.7) = 3 rounddown(-3.7) = -4 Parameter names in formulas are case sensitive. For example, if a parameter name begins with a capital letter, such as Width, you must enter it in the formula with an initial capital letter. If you enter it in a formula using lower-case letters instead, for example, width * 2, the software will not recognize the formula. Note: It is recommended that you do not use a dash (-) when naming parameters. |
