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.

Answer 1

[Matt J]

x=0.147;

floor(x*100)/100

ans = 0.1400

Answer 2

[Les Beckham]

x = [0.143 0.147];
floor(x*100)/100

ans = 1×2

0.1400 0.1400

Answer 3

Example:

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

Y = 0.1400

Someone ahd same question before. Next time, try to Google your question before asking.

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.

Y = 0.1500

The answers from Matt J and Les Beckham are correct.

True, I just reffered to someone else's answer.
