Assign values to expressions

API Scope	Command	Description
rv.V	a ==: 1*IN \| unit1, unit2, decimal \| label	[2] Define values \| ==:
rv.V	c <=: expression \| unit1, unit2, decimal \| label	[3] Assign expression values \| <=:
rv.V	c :=: func(x,y) \| unit1, unit2, decimal \| label	[4] Assign function values \| :=:
rv.V	a <= c \| unit, decimal, text1, text2 \| label	[5] Compare values \| <=

[2] Define values | ==:#

Defines a value and writes it to the file vdocnum-s.csv where num is the docnumber and s is the section number. The file is written to the folder stored/vals unless singledocB is set to True in the comment variable.

The stored values can read and defined in other rivt files using the VALUES command.

Syntax:
    c ==: 5*unit | unit1, unit2, decimals | label, *num,nonum*

Example:
    D_1 ==: 10*IN | IN, M, 3 | beam depth, num

File Types	.csv
Doc Types	text, PDF, HTML

[3] Assign expression values | <=:#

Assigns a value to an equation and writes the values to a file vdocnum-s.csv where num is the doc number and s is the section number. The file is written to the folder stored/vals unless rv single doc is set to True in which case values are stored in the rivt file folder (root).

The label is a reference printed with the equation. The units specify the result expressed in two different units. The integer specifies the number of places after the decimals.

Syntax:
    b <=: a * 10*FT | unit1, unit2, decimals | label, num;nonum

Example:
    b_1 <=: E_1 * 12.1*IN^2 | KIP, KN, 2 | Std. 123, num

[4] Assign function values | :=:#

Assigns a value to an equation and writes the values to a file vdocnum-s.csv where num is the doc number and s is the section number. The file is written to the folder stored/vals unless rv single doc is set to True in which case values are stored in the rivt file folder (root).

The label is a reference printed with the equation. The units specify the result expressed in two different units. The integer specifies the number of places after the decimals.

Syntax:
    c :=: function name() | unit1, unit2, decimals | label, num;nonum

Example:

    c_1 :=: func1(a,b) | KIP, KN, 2 | ACI 318-19 Table 22.5.5.1, num

[5] Compare values | <=#

Format to text1 if comparison is true and text2 if false.

Comparison operators:

==    Equal x == y
!=    Not equal     x != y
>     Greater than  x > y
<     Less than     x < y
>=    Greater than or equal to x >= y
<=    Less than or equal to x <= y
