Rounding the value of levels.

[YahyaRafique]

Hey guys

Is there a way of rounding the value of levels to for example 2 decimal places?

use level = INT(-level + (integer((level + 0.5) * 100) / 100) )

If your question is about display use %.2f as the format for the table tool or custom tables/reports. If you are asking about computation then something similar to what JJ such as

rounded level = INTEGER(level * 100.0 + 0.5)/100.0

should work, though I can't think of a case where this would be very helpful.

If you're using Vensim DSS, it's handy to put JJ's formula in a macro, like

:MACRO: ROUND(x,digits)
ROUND = INTEGER(x*10^digits+0.5)/10^digits
~ x
~ |

:END OF MACRO:

a test:

digits=
1
~ [-2,2,1]
~ |

test x=
ROUND(453.123,digits)
~
~ |

Note that precision is also limited by the floating point format.
