Add$ – Floating Point Calculation Function**






Floating Point Calculation Function


Description

The Add$ function adds two strings representing floating point numbers.

Usage

As only integers are supported numbers in WinTask, calculation on floating point numbers is done using their string representation.

Syntax

res$=ADD$(a$,b$[,rc])

Parameters

a$, b$ are the strings representing the two floating numbers to add.

rc, optional numeric return code.

Values are:

  • 0 if successful operation
  • 1 invalid operation because parameters are incorrect (for instance, the string can’t be considered as a number)
  • 2 if operation causes overflow

Return Value

rcs$, string representing a$ + b$.

Examples

Add$("13.56","145.789") 'gives "159.35"
Add$("-45.678","34.8976") 'gives "-10.78"
#Precision=3
Add$("567.34257","45.343") 'gives "612.686"
