可以用心体会一下
The fourth option 'd' returns the decimal expansion of t up to the number of significant digits specified by digits: sym(t,'d')

ans =
.10000000000000000555111512312578
The default value of digits is 32 (hence, sym(t,'d') returns a number with 32 significant digits), but if you prefer a shorter representation, use the digits command as follows: digits(7)
sym(t,'d')

ans =
.1000000
