Toka Tutorial: Lesson 4

Lesson 4: Basic Math and Working With Numbers

Toka provides a very basic set of math functionality, sufficient for many purposes. The functions are:

  +        ( ab-c )    Add TOS and NOS
  -        ( ab-c )    Subtract TOS from NOS
  *        ( ab-c )    Multiply TOS by NOS
  /mod     ( ab-cd )   Divide and get remainder

In addition, the standard bootstrap adds some additional operations:

  1+       ( x-y )     Increase value on stack by 1
  1-       ( x-y )     Decrease value on stack by 1
  negate   ( x-y )     Invert the sign of TOS
  /        ( xy-z )    Divide two numbers
  mod      ( xy-z )    Divide two numbers and get remainder
  not      ( x-y )     Invert the value 'x'
  */       ( abc-d )   (a*b)/c
