OTL Syntax

FloatValue = AbsoluteValue(QuantityTerm);
FloatValue = Math.Sin(QuantityTerm);

Description

Generally whenever Quantity values are used in OTX actions or terms for which no specific definition is provided regarding the behaviour in the case of Quantity arguments, an OTX runtime will use the Quantity's otx:ToFloat value for computation. For example, if a Quantity 12.4 km/h is used as an operand to the math:Sin term, the Float value 3.44 (that is, the Quantity’s normalized value 3.44 m/s) will be used as input for the operation. Note that the display precision does not have any effect in this case.

Return Value

The Term returns the value, see table below.

In OTX, Terms are categorized according to its return data type!

Data Type	Description
Float	The Float value of the Quantity’s normalized value.

Properties

OTL Examples

/// Local Declarations

Float Float1 = 0.0;

/// Flow

// The assignment below should have the returned value -3.44 (from 3.44 m/s)
Float1 = Negate(12.4 [@Unit, "BL_DataLibraMIB.odx", "km/h", -1]);
// The assignment below should have the returned value -0.885574278929912
String1 = Math.Cos(1234.5  [@Unit, "BL_DataLibraMIB.odx", "km/h", -2]);
