Add a percent sign after a number, and the number will be reduced to one percent. Is it right or wrong?

When the number is greater than 0, the percent sign will be reduced by 100 times, such as 1% = 0.01
When the number is less than 0, the percent sign is 100 times larger, for example - 1% = - 0.01, which is 100 times larger than the original
