Initializing float value in C

When do we initialize the value of a float to be negative or positive? I recently saw

"float userInput = -1.0;"

but what about

"float userInput = 1.0;"

Are there differences between the two, and when would one be used over the other?

A more detailed example below:

 int main(void)
{
 float input = -1;
 int z = 0;
 int counter = 0;

 do
 
 printf("The amount of changed owed(in dollars) is ");
 input = get_float();
