MATLAB: How to restrict a decimal number to 2 significant decimal places

Question

I am using a decimal number as follows

x = 3.43 on my command window

I want this number to be used as a single data type, which means I have to write as follows

x = single(3.43)

I am trying to see how long the decimal places are precisely correct for that I am using

format long

However I am facing problem when I try to convert and decimal number into single data type equivalent decimal number

x = single(3.43)

x =

single

3.4300001, this 1 at the end is not required for my calculations, as it creates rounding off problems in my simulation(Simulink)

let me know how can I restrict this value.

Thanks
