JavaScript multiplying by 100 giving weird result [duplicate]

Question

I have:

var a =  0.0532; var b =  a * 100; 

b should be returning 5.32 but instead it's returning 5.319999999999999. How do I fix this?

Answer 1

you should use .toFixed()

FIDDLE

var a =  0.0532; var b =  a * 100; b.toFixed(2);     //specify number of decimals to be displayed
