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()

NOTE: 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. 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 Since Arma 3 v1.71.141859 an alternative syntax is added, which takes no number and returns Nothing. Instead it acts as keyword and switches engine Number to String global conversion in 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. For example: systemChat str position player; call { toFixed 6; systemChat str position player; }; systemChat str position player; toFixed -1; systemChat str position player; The result is:

• [11580.3,11797.7,0.00146675]
• [11580.341797,11797.737305,0.001467]
• [11580.341797,11797.737305,0.001467]
• [11580.3,11797.7,0.00146675]

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

Examples

Example 1:

123 toFixed 2; //"123.00"

Example 2:

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

Example 3:

Convert position to string preserving position precision: 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]"
