having two decimal places for realstr function

[tristanbryce7]

Hey, i was hoping if anyone knew the method to draw a "real" number in turing using Font.Draw but have the output in to only 2 decimals

Instead of using realstr use frealstr or erealstr

[tristanbryce7]

i looked at the syntax and tried it accordingly but it didnt work ;(

[Tony]

in which way did it not work?

[tristanbryce7]

sorry. i am on mobile lol. as soon as i get on comp ill tell you

[tristanbryce7]

Ok, so I put
frealstr (14.245,4,1)
but it said expression is not a procedure. I'm pretty sure i got the synntax wrong

[Tony]

and what do you get? How is that different from what you expected to get?

edit:
right, this is a function that is returning a result, and Turing forces you to do something (anything) with the result. For example, you can print it to screen

I have no clue how to output the result . I have

frealstr (14.245,4,1) so far, but I try out putting it , but I dont know how to combine this frealstr with a "put" statement

Easy: putting "put" before any expression will output the result to the screen
Eg
put 45 * round (2.36)

The window now has "90" written in the TL corner

I feel like an absolute idiot lol, never thought it could've been so simple

[evildaddy911]

when i want to output a number rounded to a certain # of decimals, i use this function:

Turing:

function roundStr (num : real, places : int) : string     var final : string     final := intstr (round (num * 10 ** places))     final := final (1 .. * -places) + "." + final (* -places + 1 .. *)     result final end roundStr
