Description

Description:

Converts a number into a string, keeping the specified number of decimals. If the desired number of decimals is higher than the actual number, nulls are added to create the desired decimal length. This command is almost identical in behaviour to JavaScript toFixed()

The alternative syntax acts as keyword and switches engine's Number to String global conversion into desired format, from the moment it is applied until the end of script. To reset output back to default at any time, use toFixed -1 - see Example 5.

ⓘ

Converted number is never presented in scientific notation unlike with other number to string commands. Also Arma's default string conversion limits numbers to 6 significant figures, whereas with this command it is possible to preserve some extra precision - see Example 6.

Syntax

Syntax:

number toFixed decimals

Parameters:

number: Number - number to convert

decimals: Number - number of decimals to display (range 0-20)

Return Value:

String

1.72

Alternative Syntax

Syntax:

toFixed decimals

Parameters:

decimals: Number - number of decimals to display (range 0-20). -1 to reset to default number of decimals

Return Value:

Nothing

Examples

Example 1:

Copy

123 toFixed 2; // "123.00"

Example 2:

Copy

2.34 toFixed 1; // "2.3" 2.35 toFixed 1; // "2.4"

Example 3:

Convert position to string preserving position precision:

Copy

fn_posToString = { format [ "[%1,%2,%3]", _this select 0 toFixed 8, _this select 1 toFixed 8, _this select 2 toFixed 8 ] }; str getPos player; // "[3231.05,171.802,0.00143862]" getPos player call fn_posToString; // "[3231.04882813,171.80192566,0.00143862]"

Example 4:

Same as Example 3 only using new alternative syntax:

Copy

str getPos player; // "[3231.05,171.802,0.00143862]" toFixed 8; str getPos player; // "[3231.04882813,171.80192566,0.00143862]"

Example 5:

Copy

systemChat str position player; // [11580.3,11797.7,0.00146675] call { toFixed 6; systemChat str position player; // [11580.341797,11797.737305,0.001467] }; systemChat str position player; // [11580.341797,11797.737305,0.001467] toFixed -1; systemChat str position player; // [11580.3,11797.7,0.00146675]

Ideal to be used when saving data to a database when more precise positioning is required.

Example 6:

Copy

str (pi/100000); // "3.14159e-005" - scientific notation (pi/100000) toFixed 10; // "0.0000314159" - no scientific notation str pi; // "3.14159" - 6 significant figures (default) pi toFixed 6; // "3.141593" - forced to 7 significant figures pi toFixed 7; // "3.1415927" - forced to 8 significant figures
