Band Strength sets the strength of all bands to the value you specify.

Band Strength allows you to enter an exact value, which is difficult using the sliders found in the Set Strength dialog or other Foldit recipes.

The strength value must be between 0 and 10.

Scientific notation is accepted. For example 1.2E-1 translates as "1.2 time 10 to the minus 1 power", or 0.12.

Band Strength is also an example of how to check user input for errors and provide an error message.
