Hi all......

How do I convert a Number into a String with exactly 2 decimal places?

Thanks & Regards

Hi...

When formatting money for example, to format 6.57634 to
6.58, 6.5 to 6.50, and 6 to 6.00?

Rounding of x.xx5 is uncertain, as such numbers are not
represented exactly.

N = Math.round(N*100)/100 only converts N to a Number of value
close to a multiple of 0.01; but document.write(N) does not give
trailing zeroes.

ECMAScript Ed. 3.0 (JScript 5.5 [but buggy] and JavaScript 1.5)
introduced N.toFixed, the main problem with this is the bugs in
JScripts implementation.

Most implementations fail with certain numbers, for example 0.07.
The following works successfully for M>0, N>0:

function Stretch(Q, L, c) { var S = Q
if (c.length>0) while (S.length<L) { S = c+S }
return S
}
function StrU(X, M, N) { // X>=0.0
var T, S=new String(Math.round(X*Number("1e"+N)))
if (S.search && S.search(/\D/)!=-1) { return ''+X }
with (new String(Stretch(S, M+N, '0')))
return substring(0, T=(length-N)) + '.' + substring(T)
}
function Sign(X) { return X<0 ? '-' : ''; }
function StrS(X, M, N) { return Sign(X)+StrU(Math.abs(X), M, N) }

Number.prototype.toFixed= new Function('n','return StrS(this,1,n)')


i hope this will help you....

thnx...

a = (32767).toString(16) // this gives "7fff"
b = (255).toString(8) // this gives "377"
c = (1295).toString(36) // this gives "zz"
d = (127).toString(2) // this gives "1111111"

function toRadix(N,radix)
{
var HexN="", Q=Math.floor(Math.abs(N)), R;
while (true)
{
R=Q%radix;
HexN = "0123456789abcdefghijklmnopqrstuvwxyz".charAt(R)+H exN;
Q=(Q-R)/radix; if (Q==0) break;
}
return ((N<0) ? "-"+HexN : HexN);
}
