Converting

[TurtleProgrammer]

Is there a way to convert say: 1.019 to 1.0 and store the result in a variable? I found PRINT USING, but of course that prints to the screen which I don't want to do.

[srvaldez]

use format

Code: Select all

#include "string.bi"

dim as double x=1.019
dim as string s

s=format(x,"##.0")
print s
sleep

[MrSwiss]

Double to INT-type conversion (without any string):

Code: Select all

' numeric version
Dim As Double d = 1.019
Dim As Long   l = fix(d)

Print l, d

Sleep

What type of variables (string/double/single)? In and out?
Do you want to round the result?

Yes, there are several ways, but you need to know exactly how you want to convert:

Code: Select all

#include "crt\math.bi"

dim as double numd
dim as integer someint
print "fix", "int", "floor", "ceil", "double"
for numd=-1.2 to 1.2 step 0.1
  print fix(numd), int(numd), floor(numd), ceil(numd), numd
next

' the conversions
someint=fix(numd)
someint=int(numd)
someint=floor(numd)
someint=ceil(numd)

sleep()

Code: Select all

Is there a way to convert say: 1.019 to 1.0 and store the result in a variable? I found PRINT USING, but of course that prints to the screen which I don't want to do.

Code: Select all

dim as single x = 1.019, i
i = fix(x)
'print i

That should be exactly what you want.

[jj2007]

That should be exactly what you want.

So, from "say: 1.019 to 1.0" you deduct that fix() is exactly what he wants?

[lizard]

Why not?
