Four. Obviously non-zero numbers count. Also, zero's on the right side of a decimal always count if they come after a non-zero number, which could be on either side of the decimal, regardless of if a non-zero number comes after them. Rules like this one are ridiculous to memorize, but thinkg of it as though you were taking measurements and reporting them to someone who did not know how you took them:
If you were using a ruler marked only in whole inches (a yardstick maybe) and you measured something to be 1", you'd write it just like that. Writing 1.000 implies that you were able to measure it that precisely, as if you used a digital caliper.
Trailing zero's don't always count. The number 15,000 has only two sig-figs, because you couldn't leave off the trailing zero's. 15,000. has five sig-figs because of the decimal.

Whole numbers always have an infinite number of sigfigs.

One. You tend not to use trailing zeros.
