limit_warn()
Limits the value to default, mininimum or maximum value, issues a warning
Syntax
limit_warn(Parameter, MinValue, MaxValue, Default, Name)
Arguments
| Name | Description | Range | Type | Default | Required |
|---|---|---|---|---|---|
| Parameter | Parameter to be limited | (-∞, ∞) | integer, real | no | |
| MinValue | minimum value for the parameter | [-LargestReal, LargestReal] † | integer, real | no | |
| MaxValue | maximum value for the parameter | [-LargestReal, LargestReal] † | integer, real | LargestReal | no |
| Default | default value for the parameter | (-∞, ∞) | integer, real | -LargestReal | no |
| Name | name of parameter | string | no | ||
| † LargestReal = 1.79769313486231e+308 | |||||
Examples
Assume a circuit has a resistor R1. If you want to limit the value of the resistor to a minimum value of 10 ohms, a maximum value of 49 ohms, and a default value of 40 ohms, then set the parameter R of the resistor as:
R = limit_warn(Rval, 10, 49, 40, "R1 value")
where Rval is defined as:
Rval = 50
this displays a warning "While evaluating expression 'R1.R': 'R1 value limited to 49'"
Notes/Equations
This function is used to limit the value of a parameter to a default, minimum or maximum value. If the first parameter value is not set, then the value of the parameter is set to Default .
If MinValue is set, and if the value of the parameter is less than the MinValue, then the value is set to MinValue .
If MaxValue is set, and if the value of the parameter is greater than the MinValue, then the value is set to MaxValue .
