Format menu

#rad Angle Unit in Radians
It is usual for scientists and engineers to measure angles in radians.
#deg Angle Unit in Degrees
Degrees are am unit of angular measure in which the angle of an entire Circle is 360°.
#grad Angle Unit in Grads
Grade is a unit of angular measure in which the angle of an entire Circle is 400 grads.
#auto Automatic Mode
Automatic mode displays numbers exactly as you enter them and answers to 15 significant decimal places.
#sci Scientific Mode
Scientific mode displays a number as a mantissa - with one digit to the left of the decimal point and the user-specified number of decimal places - and the exponent
#fix Fixed Mode
Fixed mode displays numbers rounded to an user specified number of decimal places (default is 2)
#dec Decimal Places
You must follow the #sci or #fix with digits (0-15) specifying the number of decimal places, e.g. enter #sci3 in input line.
#dig Use Digit Grouping
If the Digit Grouping is checked, then the number is shown in decimal format with a separator (small space) that separates groups of three digits from both sides of the decimal separator.
#fun Use Function Separator
Use this option if you want to enable/disable the colon (:) as function separator.
Decimal Separator
You can use the dot (.) or comma (,) as decimal separator
Dot (0.5) #dot
Comma (0,5) #comma
Save Current Settings
The Save method persists any configuration settings that have been modified in Format and View menu. If a configuration file does not exist at the physical location where c4c.exe is stored, a new configuration file will be created to contain any settings that are different from the default configuration.
Reset to Defaults
Fill the c4c.cfg file with default values. Deleting the c4c.cfg file will also set the application back to the original default settings.
