how can I convert a decimal to an integer?

how can I convert a decimal to an integer?

example

1.232422->1

2123.43242322->2123

Answer 1

[Oleg Komarov]

• fix to strip all the decimals
• round can change the integer part

fix  (1.9) % 1
round(1.9) % 2

Answer 2

[Szymon Buchaniec]

All the proposed answers:

• round(x) - round to the closest integer to x
• floor(x) - round to the nearest integer less or equal to x
• ceil(x) - round to the nearest integer greater than or equal to x
• fix(x) - round to the nearest integer towards 0 (floor(x) for x >=0 and ceil(x) for x<=0)

does not convert the number, but only rounds it. Type of the number is still the same. To convert a decimal (double) number to an integer, one needs to use Conversion Functions. Rounding is automatic, but can be chosen explicitly. Examples:

• uint16(1.8) -> 2
• int32(floor(1.8)) -> 1

Answer 3

[Mads Svendsen-Tune]

There is a function: round()

Answer 4

[Willem Dorff]

floor() to round down to nearest integer

ceil() to round up to nearest integer
