Converts the nominated Parameter Value string to a number, using the stipulated unit type.

Syntax

StrToNumber(Value : String , Unit : String) : Number

Example Usage

Converts the Value string returned by the CapacitanceValue Parameter to a number, using Capacitance (F) as the unit, then returns all objects with a Value less than 2nF (2e-9 in scientific notation).

Notes

A scripting error will be thrown if the Value string cannot be converted to a number. To allow for this situation, use the StrToNumber function, which returns a nominated default number if the conversion fails.

The unit-aware string-to-number converter function accepts a large range of Unit type definitions, including:

• V – Voltage
• A – Current
• Ohm – Resistance
• Z – Impedance
• F – Capacitance
• H – Inductance
• G – Conductance
• W – Power
• Hz – Frequency
• Q – Charge
• C – Temperature
• dB – Decibels
• % – Percent
• m – Length
• Kg – Mass
• s – Time

The converter accepts standard value scaling factors (micro, kilo, mega, etc.,) and, therefore, Parameter strings containing prefix abbreviations such as mV, uA, kHz, etc.

Several value constructs are also supported. For example, the same resistance value can be represented as:

• 2k2
• 2.2k
• 2200
• 2,200

Summary

Converts the nominated Parameter Value string to a number, or a default number, using the stipulated unit type.

Syntax

StrToNumber(Value : String , Unit : String , Default : Number) : Number

Example Usage

StrToNumberDef(ParameterValue('VoltageRating'),V,10)  >  50
Converts the Value string returned by the VoltageRating Parameter to a number, using Voltage (V) as the unit, then returns all objects with a Value greater than 50V. If the Parameter string or unit is unrecognized (can't be converted), a default value of 10 is returned.

StrToNumberDef(ParameterValue('VoltageRating'),'V',6) Between 10 And 50
Converts the Value string returned by the VoltageRating Parameter to a number, using Voltage (V) as the unit, then returns all objects with a Value rating between 10V and 50V. If the value cannot be read, a voltage of 6V (the defined default value) is assumed.
