Class NumericNCWord

"NumericNCWord", or in other words "Register", is an object that helps you quickly and conveniently convert numeric values to a text format that the CNC machine understands. For example, you can easily convert the coordinate value x = 5.18 to the string "X0005.180". This corresponds approximately to one word in the output G-code.

Optionally, NumericNCWord can also help you to filter the output. It contains two values - current v and previous v0 (which has already been output earlier). If both of these values are the same, then re-output the value can be skipped automatically.

Constructors

NumericNCWord(string, double)

The main constructor to create a new instance of the NumericNCWord. It is used the "format" string parameter to define the all formatting rules for the NumericNCWord.

For example, the "format" parameter can be: "X = {-####!0##};". The formatting rules are below.

1. The curly braces divide the expression into three parts.
2. Anything to the left of the braces is assigned to the Address property and passed to the output line unchanged (here is "X = ").
3. Anything to the right of the braces is assigned to the TailString property and also goes to the output string as it is (here is ";").
4. The expression inside the braces defines the formatting rules applied to the current v value (here is "-####!0##"). It can only include these characters "-+.!_#0".
5. If the first character in braces is "-", then the sign of the number will output only for negative numbers. It corresponds to SignMode property value Minus.
6. If the first character in braces is "+", then the sign of the number will output both for positive and negative numbers. It corresponds to SignMode property value PlusAndMinus.
7. If the first character in braces is not "+" or "-", then the sign of the number will not output at all. It corresponds to SignMode property value No.
8. One of the characters ".!_" in curly braces separates the integer part from the fractional part and determines how to output the decimal point.
9. The point "." means the optional output, so the decimal point will output for fractional numbers, and for integers it will be skipped. It corresponds to the property PointMode = No.
10. An exclamation point "!" indicates a required output, so the decimal point will output both for fractional and integer numbers. It corresponds to the property PointMode = Always.
11. The underscore "_" or the absence of any of the characters ".!_" at all means that the decimal point will never be output. It corresponds to the property PointMode = No.
12. The number of characters "0" or "#" before the characters ".!_" indicates the number of characters allowed before the decimal point. It corresponds to the property DigitsBeforePoint.
13. If at least one of the characters before the point is zero "0", then non-significant zeros are required. It corresponds to the property LeadingZeroes = true.
14. If all characters before the point are "#", then non-significant zeros will not output. It corresponds to the property LeadingZeroes = false.
15. The number of characters "0" or "#" after the characters ".!_" indicates the number of characters allowed after the decimal point. It corresponds to the property DigitsAfterPoint. The number will be rounded to the specified number of digits before output.
16. If all characters after the point are "#", then non-significant zeros will not output. It corresponds to the property TrailingZeroes = No.
17. If all characters after the point are "0", then non-significant zeros are required. It corresponds to the property TrailingZeroes = Yes.
18. If the first character after the point is "0" and the rest are "#", then only first non-significant zero will output and the rest will be skipped. It corresponds to the property TrailingZeroes = OneOnly.

Unstable

Returns "True" if the NCWord is in the so-called "Unstable" state after the call of Reset() method. Actually it checks that the previous v0 value is equal to the "undefined" value ("double.MaxValue"). This state means that the NCWord will NOT output on the next call of Out() or Form(). But it will output just after the first change of the current v value.

Declaration

public override bool Unstable { get; }

Property Value

Together with the previous v0 value and the NCBlock, it can be used to filter the output. If v == v0, then the output line formed by the NCBlock.Out and NCBlock.Form commands will not include this NumericNCWord (it will be skipped).

Declaration

public double v { get; set; }

Property Value

Type	Description
double

v0

The previous v0 value of the NumericNCWord. Together with the current v value and the NCBlock, it can be used to filter the output. If v == v0, then the output line formed by the NCBlock.Out and NCBlock.Form commands will not include this NumericNCWord (it will be skipped).

Declaration

public double v0 { get; set; }

ValuesSame

The property is "True" only if the current value v and the previous value v0 form a completely identical output string.

Declaration

public override bool ValuesSame { get; }

Property Value

Type	Description
bool

Overrides

NCWord.ValuesSame

Methods

Hide(double)

Switches the NCWord to the Unchanged state. It means that the NCWord will NOT output on the next call of Out() or Form().

Additionally it assigns the speciefied number to the current v value of the register.
