Calculation Formula Guide
SureForms allows you to create dynamic calculation boxes using simple math functions. This guide outlines the supported syntax and available functions.
Supported Syntax
Use functions without the Math. prefix. For example:
ceil() ✅
Math.ceil() ❌
Sample Formulas
ceil({ form:number1 }) → Rounds up to nearest integer
floor({ form:number1 }) → Rounds down to nearest integer
{ form:number1 } mod ({ form:number2 }) → Returns the remainder of division
Supported Functions
🔢 Rounding and Absolute Value
| Function | Description |
|---|---|
abs(x) | Absolute value |
ceil(x) | Round up |
floor(x) | Round down |
round(x) | Round to nearest integer |
trunc(x) | Remove fractional part |
📐 Trigonometric Functions
| Function | Description |
|---|---|
sin(x) | Sine |
cos(x) | Cosine |
tan(x) | Tangent |
asin(x) | Arc Sine |
acos(x) | Arc Cosine |
atan(x) | Arc Tangent |
📈 Exponential and Logarithmic
| Function | Description |
|---|---|
exp(x) | e raised to the power x |
log(x) | Natural logarithm |
log10(x) | Log base 10 |
sqrt(x) | Square root |
cbrt(x) | Cube root |
🌐 Hyperbolic Functions
| Function | Description |
|---|---|
sinh(x) | Hyperbolic sine |
cosh(x) | Hyperbolic cosine |
tanh(x) | Hyperbolic tangent |
asinh(x) | Inverse hyperbolic sine |
acosh(x) | Inverse hyperbolic cosine |
atanh(x) | Inverse hyperbolic tangent |
Notes
- Only
function(x)format is currently supported. - The
Math.prefix does not work in formulas. - For clarity, avoid using JavaScript-style function names like
Math.ceil(x).
