regarding float to string conversion

fazul

Hi everybody

i am very new to SKILL programming, so this might be a very simple question ... Actually i want to do

Float to String converstion . I am working on IC5.1 framework.

upon searching i found this method

strVar  = 1.23e4

ftVar = sprintf( nil "%.2e" strVar)

is there any other neater way of doing ? the problem i found with the above method is that even smaller float values say 23.4 will be

forcibly converted to scientific notation "2.34e+01" .. which looks pretty ugly(aestically)  on my ReportField.

background :

It seems like ReportField in IC51 doesnt support scientific notation for float values.. So i am stuck on doing the Float2String conversion

before displaying it in the ReportField...

hope i made my problem clear. Please advice me if there is a better way of doing this.

thanks in advance,

Have a great day

  •  Hi Fazul,

    You could try the "%g" format which chooses the most efficient way to display the number, which is usually aesthetically pleasing.  Also you can specify the number of digits after a decimal point, so if you said "%5.2f" for the format specifier you would get "23.40" when the input was 23.4

     By the way, if you are assigning the result of "sprintf" to a variable, you can just say:

     sprintf( ftVar "%.2e" strVar)

    Instead of:

     ftVar = sprintf( nil "%.2e" strVar)

    I hope that the above answers your question.

    regards,

    Lawrence.

  • Refer to some documentation on the common printf function, an internet search for printf or a C / C++ reference manual would get you there. The format string is what controls the format, the number is being correctly formatted according to the format string that you have specified, there are "pretty much" "boundless" possibilities for the format string. Experiment with the format option to get your desired results.

  • You could also use the functions aelEngNotation(), aelSuffixNotation() or aelScientificNotation() - depending on what you want.
