Detailed Description

Sum of two real numbers.

Definition at line 153 of file real.h.

Constructor & Destructor Documentation

add()

vita::real::add::add ( const cvect &  c = {0} )

inlineexplicit

Definition at line 156 of file real.h.

Member Function Documentation

associative()

bool vita::real::add::associative ( ) const

inlinefinalvirtual

Is the symbol subject to the associative law of arithmetic?

Returns

true if the function is associative

OP is associative iff:

a OP (b OP c) = (a OP b) OP c = a OP b OP c

This information can be used for optimization and visualization.

Note

• Terminals haven't arguments and cannot be associative.
• Default (safe) value is false.

Reimplemented from vita::function.

Definition at line 158 of file real.h.

display()

std::string vita::real::add::display ( format  ) const

inlinefinalvirtual

Returns

the name of the function

Warning

Specific functions have to specialize this method to support different output formats.

Reimplemented from vita::function.

Definition at line 160 of file real.h.

eval()

value_t vita::real::add::eval ( symbol_params &  ) const

inlinefinalvirtual

Calculates the value of / performs the action associated with the symbol (it's implementation specific).

Implements vita::symbol.
