Numerical expressions in NAPA Steel connection settings

A numerical expression is a string from which a number is calculated.

A numerical expression can contain the following operators:

Multiplication and division take precedence over adding and substracting.

A numerical expression can contain brackets ().

A number preceded by the % character is replaced by the corresponding value of the NAPA Steel parametric shape. For example, in stiffener conversion:

T*100*8*80*10 => %1 = 100, %2 = 8, %3 = 80, %4 = 10

Or in conversion of openings:

RR*100*120*40 => %1 = 100, %2 =120, %3 = 40

Note: A numerical expression cannot contain spaces.

Some examples of numerical expressions:

-30

(%2+5)*0.5

100/%1

2*(%1-(%2/2))
