how to round 10.5 to 10 ?

hello I want to round down from 10.5 to 10 is there a command for this operation ?

[Walter Roberson]

Is the question about the rounding of values that end in 0.5 exactly, since round() typically rounds those up?

both fix and floor will give the same answer for positive decimal numbers (if your intention is to round down regardless the decimal value)

But they will produce different results for negative decimals:

1. fix

fix rounds towards 0

fix(10.5) = 10
fix(-10.5) = -10

2. floor

floor rounds towards negative infinity

floor(10.5) = 10
floor(-10.5) = -11
