tcCalc - timecode & frame calc 4+

(Overview)
This app is a calculator app that calculates timecode and frames.

(Feature)
-You can calculate the time code as if you were operating a calculator.
-The time code and the number of frames can be converted to each other.
-Various frame rates are available.
-Automatically corrects input values ​​and calculation results from zero to values ​​less than 24 hours.

(How to use)
input:
-Enter the time code and the number of frames with the number buttons (0 to 9).
-The "AC" button erases all displayed values and calculation processes. The “C” button erases the input value and calculation result.
-To delete the displayed value character by character, press the delete button.
-Up to 8 digits can be entered.

Calculation:
-The calculation method is the same as a general calculator, using symbol buttons (+,-, =).
-For example, you can use the "-" button to find the duration between times.

Display change:
-Press the "F" button to convert the displayed value to the number of frames.
-Press the "T" button to convert the displayed value to a time code.
-The display can be changed even during the calculation.

Change frame rate:
-Press the "fps" button to display the screen for selecting the frame rate. Select the frame rate you want to change.
-The frame rate can be selected from 23.98fps, 24fps, 25fps, 29.97fps, 30fps, 50fps, 59.94fps, 60fps.
-29.97fps and 59.94fps use the drop frame (DF) counting method, and the others use the non-drop frame (NDF) counting method.
-If you select hh:mm:ss, you can calculate the time (hours, minutes, seconds) without using frames.

Copy and Paste:
-By long-pressing the value of the calculation result, you can copy the value or paste the already copied numerical value.
-You can copy numbers to and paste from other applications (the Calculator and Notes of the standard iPhone applications, etc.).
-For characters that include non-numeric values, only the numerical values ​​are pasted in order. In the frame display mode, numbers after the decimal point are truncated and the remaining numbers are pasted.

(Others)
-Press the ”m+”, ”m−”, ”mr”, ”mc” buttons to use the memory function. The displayed value is stored in an independent memory. The stored value is displayed in the upper right corner of the screen.
-By pressing the "+/-" button, you can change the sign of the input value and the calculation result. Negative values are 24 hours minus that value.
-The time code mainly conforms to the SMPTE 12M-1 standard.
-59.94fps is based on the counting method commonly used in Adobe Premiere Pro.
