See the answer by other, especially if you have already code using the printf method, could be to change the locale of your shell session using 'export'.īut then this negates the printf simplicity. Remember that scale only works on division and to divide your input sum by one. It doesn't need to be piped as in some of the examples. Industry Standard Presets Over 10 different preset video and film formats, and over 11 preset frame rates and film units. This is what happens if your computer has its number system set to use commas: printf %.2f 573,5489 Timecode displays four user-definable units at once, allowing you to view 24 fps, 25 fps, rolls of film and frame counts at the same time. According to Wikipedia > Decimal_separator the comma is noted as an ISO/IEC Directive. However, if you have hard coded a decimal point, you should know that your code will probably fail if used one of the many countries that use a comma separator.Ī surprising number of countries actually do use this & many of them in Europe. The printf method is very neat, easy to use & listed in lots of how to's. If [ '$1' != '$ '| bc -l)# (-l= libmath for fp)Ĭ: # subtract each amount of time from tt and store itįrames=$(echo '$tt * 75' | bc ) # 75 frames /secįrames=$(echo '$frames/1' | bc ) # truncate to whole #ĭ: #convert to proper format with printf (bash builtin)

I'm still looking for a pure bc answer to how to round just one value within a function, but here's a pure bash answer: #!/bin/bash This is why my script has an additional third parameter. But since we (unfortunately) have no built-in abs() function at our disposal (unless we code one), we will simply negate the argument if it's negative.īesides, it proved very cumbersome to work with the quotient as a parameter (since for my solution, I must be able to access the dividend and divisor separately). Mathematically spoken, we'll just compute the absolute value of the argument and still add 0.5 as we normally would. It is actually simple: there is no need to explicitly add a hardcoded '-0.5' variant for negative numbers. (( $(bc <<< '$vorig < 0') = 1 )) & r=$(bc <<< '$r * -1')Įcho 'Insert the price you want to calculate:'Įcho & read -p 'Press any key to continue.' # have to add the minus sign again for the resulting value. however, since value was only negated to get correct rounding, we

Cronitor is easy to integrate and provides you with instant alerts when things go wrong. We created Cronitor because cron itself cant alert you if your jobs fail or never start. # the round function (alternate approach): # - inspired by user85321 (original author) # - loosely based on the function 'round()', taken from
