Hello,
I have to deal with numbers with a decimal part as quarter, coming
from two systems with different way to show decimals. I need to tell
R these are in fact the same number.
On one side my number are formatted this way : 2.2 , 2.4 and 2.6. On
the other side, I have 2.25, 2.50 and 2.75.
All numbers are in fact 2.1/4, 2.1/2, 2.3/4.
How can I tell R 2.2 is 2.25, 2.4 is 2.50 and 2.6 is 2.75 ?
vec <- c( 2.2 , 2.4 , 2.6)
trunc(vec) + (vec-trunc(vec))*(2.5/2)
[1] 2.25 2.50 2.75
TY for any help.
