I made a program for managing current account
but what I want to print the variable myvar # = 45.10
on the screen it appears to me 45.0999984741
how must I do to print only the first two decimal places?
thanks

This snippet might help.

+ Code Snippet

var# = 45.10
print var# ` not quite sure why this differs from the next line ...
print str$(var#) ` convert value to a string
print str$(var#, 2) ` ditto but accurate to 2 decimal places
wait key

if you need your variable to remain a numeric value for any reason try this:

+ Code Snippet

myvar#=45.0999984741:myvar#=int(myvar#*100):myvar#=myvar#/100

How would that help? Try this:

+ Code Snippet

myvar#=45.0999984741:myvar#=int(myvar#*100):myvar#=myvar#/100
print str$(myvar#)
wait key

The strange value is almost certainly a result of trying to convert a decimal float to a binary one.

I managed !!

myvar#=45.10
myvar#=myvar#*100
Sum$=str$(myvar#): L=Len(sum$)
Sum$=left$(Sum$,L-2) + "." + right$(Sum$,2)
print sum$

display 45.10

Thank's at all
