!PRECISION ERRORS IN DIVISION!

[gianks]

Hi.

i'm experiencing a very strange problem with division between doubles.

If i try do divide a double just rounded via MathRound by 10, often i obtain a precision error:

Ex:

879.0 / 10 = 87.9000000001

980.0 / 10 = 97.9999999999

164.0 / 10 = 16.4

Nothing wrong in multiplication (1.10 * 10 = 11.0 correct! ).

I have tested this behavior in two separated environment with same results.

Try this:

MathAbs(879) / 10

or,

NormalizeDouble(MathAbs(879) / 10, 1)
