Calculation with decimals

[fiction 11]

Hi exist a way to make a calculation in decimal and the result round off?.

 

For example...

 

[email protected] = (1/(1+10 **(((1580 - 1500)/400))));

[email protected] = (1/(1+10 **(((1500 - 1580)/400))));

 

[email protected]_new = 1500 + 32(1 - [email protected]);

[email protected]_new = 1580 + 32(0 - [email protected]);

 

_____

 

[email protected] = 0.38686317984

[email protected] = 0.61313682015

[email protected]_new = 1519.62037825 round off to 1520

 

Currently all numbers are round off to 0 when decimals exist :[

when I want to round values I check if the remainder of the division is greater than 5.
example:

.@calc1 = 237/7;
.@calc1_r = 237%7;	
if(.@calc1_r > 5) .@calc1++;
