why this simple script gives me false not ture?

[ForexGG]

$QUOTE_END = 161.10
$QUOTE_STA = 161.05

    $QUOTE_END -= 0.05
    MsgBox(0,"",$QUOTE_END & "  " & $QUOTE_STA,2)
    MsgBox(0,"",$QUOTE_END >= $QUOTE_STA,2)

isn't 161.05>=161.05?

why it gives false instead of ture?

thanks

Even just = doesn't work. I guess it's some weirdness with how AutoIt habndles floating numbers, Rounding them works fine :

$QUOTE_END = 161.10
$QUOTE_STA = 161.05

    $QUOTE_END -= 0.05
    MsgBox(0,"",Round($QUOTE_END,2) & "  " & $QUOTE_STA)
    MsgBox(0,"",Round($QUOTE_END,2) >= $QUOTE_STA)

Try rounding to 2 decimal places.

MsgBox(0,"",Round($QUOTE_END,2) >= Round($QUOTE_STA,2),2)

It's not AutoIt, it's floating point precision. There many threads on these forums discussing this issue. Edited June 8, 2009 by picaxe

This is a standard behavior of floating point math on computers. It is correct to about 14 decimal places. AutoIt gets its math from the C++ libraries used to write and compile the interpreter.
