# Script that I used

rm(list=objects())
objects()

WT <- 91
AGE <- 41
SCR <- 1.3

CCL1 <- (140-AGE) * WT / (72 * SCR)
CCL2 <- (140-AGE) * WT / 72 / SCR

CCL1
CCL2

identical(CCL1, CCL2)
identical(CCL1, 96.25)
identical(CCL2, 96.25)

CCL1*10 + 0.5
CCL2*10 + 0.5

floor(CCL1*10 + 0.5)
floor(CCL2*10 + 0.5)

as.integer(CCL1*10 + 0.5)
as.integer(CCL2*10 + 0.5)


# Same with multiplied WT
# Same in S-Plus Enterprise Developer Version 7.0.6 for Microsoft Windows :
2005
# But these are accurate in MS-Excel.
