Step

(Engine-Level Function)

Description: Transforms a continuous value into discrete steps.
Returns: Numeric
Usage: Script or steady state.
Function Groups: Rounding Math
Related to: Abs | Ceil | Int | Scale
Format: Step(X, Size, Increment)
Parameters:  
X
Required. Any numeric expression giving the value to reduce to discrete steps.
Size
Required. Any numeric expression giving the size of the steps in the X input parameter.
Increment
Required. Any numeric expression giving the size of the step in the result.
Comments:

The return value is arrived at by dividing X by Size and taking only the portion before the decimal point, then multiplying by Increment. Note that negative numbers are taken down to the next lower number (e.g. -0.1 becomes -1). If any parameters are invalid, the return value is invalid.
This function is useful for determining the coordinates for menu highlight bars and for rounding numbers to the nearest multiple of another value.

This function does calculations with double-precision floating point values and does not support 64-bit integers computations.

Examples:

p = Step( 4, 1.5, 2);
q = Step( 2.31, 2, 10);
r = Step(10, 100, 0.25);

The values for p, q and r will be 4, 10 and 0 respectively.
