I'm new at community and I'm starting with Mathematica. I'm now having a trouble with a very simple problem which for many of you might be really obvious.

In documentation N suppose to give me a precision of the second parameter:

lfToMoneyValue[number_Real] := Module [{r},
    r = N[number, 2];
    r
]

I wish i have an "Out: 5.14" so i could afterward join 'R$' since it suppose to be in 'Reais' money currency

Could anyone help me? thank you alot

Possibly something like NumberForm[...,{Infinity,2}]. See also AccountingForm. – Daniel Lichtblau Oct 21 '14 at 14:25
Try lfToMoneyValue[number_Real] := ToString@Round[number, 0.01] <> " R$" – eldo Oct 21 '14 at 14:27

Please clarify if you are looking for formatting of the number to two decimal places or if you want to actually round the number. – bobthechemist Oct 21 '14 at 14:29
Im trying to get the SAME number with 2 decimal places, not rounded, if its really easier rounded, ok, but I could take both ways – Luiz Fernando Fernandes Oct 21 '14 at 14:31
eldo - That one acctually is working fine, thank you, still i wanted to know why i can do this with pi and i cant with another Real number – Luiz Fernando Fernandes Oct 21 '14 at 14:34
