Hey everyone,,
i Have a question,,,i am making a javascript code that would like give ur interest and stuff into an output box,,when u give them the rate, time and principle amount in 3 input boxes,,,i got it working too. and then i thought of like converting them into other currencies using buttons and i got that working too but the question,,is how do i round the output numbers to the nearest whole number? here is the code i have so far

var dollar
dollar = " $"

var gb
gb = " £"

var gbper
gbper = " £ per month"

var mexi
mexi = " MXN"

var mexiper
mexiper = " MXN per month"

var euro
euro = " €"

var europer
europer = " € per month"

var per
per = " $ per month"

function us (form)
{
a=eval (form.amount.value)
b=eval (form.rate.value)
f=(b/100)
c=eval (form.time.value)
d=a*f*c
form.interest.value=d+dollar
tot=(d+a)
form.tot.value=tot+dollar
i=(12*c)
z=tot/i
form.permonth.value=z+per
}

function ita (converter)
{
a=eval (form.amount.value)
b=eval (form.rate.value)
f=(b/100)
c=eval (form.time.value)
d=a*f*c*0.761092929
form.interest.value=d+euro
tot=(d+a)
form.tot.value=tot+euro
i=(12*c)
z=tot/i
form.permonth.value=z+europer
}

function mex (converter)
{
a=eval (form.amount.value)
b=eval (form.rate.value)
f=(b/100)
c=eval (form.time.value)
d=a*f*c*11.1517
form.interest.value=d+mexi
tot=(d+a)
form.tot.value=tot+mexi
i=(12*c)
z=tot/i
form.permonth.value=z+mexiper
}

function gre (converter)
{

b=eval (form.rate.value)
f=(b/100)
c=eval (form.time.value)
d=a*f*c*0.517812759
form.interest.value=d+gb
