Rounding a decimal down

With round(x,2) I can round a number to the nearest hundredth, but how do I round down to the nearest hundredth? For example, both 0.143 and 0.147 should become 0.14.

Example:
X = 0.143;
Y = sprintf('%.2f',X);
Y = str2double(Y)

It is more efficient to keep this in the numeric domain, rather than converting to text and back.
It also does not work, because SPRINTF rounds values to the nearest digit, it does not round down:
X = 0.147;
Y = sprintf('%.2f',X);
Y = str2double(Y) % Nope, definitely not rounded down.
The answers from Matt J and Les Beckham are correct.
