how?: if a float=0.0 ..then set float=1.0

[cs1.7]

hi

how can i force "floatX" to be 1.0 ..if has a value of 0.0?

this does not work:

new Float:floatX = variableM * 100 / g_AlivePlayers;
if(floatX = 0.0)
{
floatX = 1.0;
}

= means set
== means "is equal to"

[mottzi]

new Float:floatX = variableM * 100 / g_AlivePlayers;
if(floatX == 0.0)
{
floatX = 1.0;
}

[cs1.7]

actually that can be considered as a typo.

i do have :

if(floatX == 0.0)
{
floatX = 1.0;
} and it's not working.

Floats are not like integers. Results of formulas rarely equal 0.0, so use something like this:

#define FLOAT_ZERO 0.0001 //anything lower than this is considered 0.0
if(-FLOAT_ZERO <= floatX <= FLOAT_ZERO)
{
floatX = 1.0;
}

thx..

well if g_AlivePlayers = 0 ..then the outcome of the formula is 0

will your method work then?


edit:

another question:

if variable is >30.0 --> set it to 30.0
if it is <15.0 -->set it to 15.0

how do i create such a code most efficiently? Can i create this via one if sentence?

here i need two if conditions to achieve my goal:
if(variableX > 30.0)
{
variableX = 30.0;
}
else
{
variableX = MAXm / 400.0;
}

if(variableX < 15.0)
{
variableX = 15.0;
}
else
{
variableX = MAXm / 400.0;
}

Dividing by zero will result in an error.

new Float:variable
variable = floatclamp(variable, 15.0, 30.0)

if(variableX > 30.0)
{
variableX = 30.0;
}
else
{
variableX = MAXm / 400.0;

if(variableX < 15.0)
{
variableX = 15.0;
}
else
{
variableX = MAXm / 400.0;
}



I don't understand this code.

hmm.. it didnt. the formula returned a value of 0 if aliveplayers were 0.

I don't understand this code.

how can the below code made more efficient?
new Float: variableX = MAXm / 400;

if (variableX > 30.0)
{
variableX = 30.0;
}

if (variableX < 15.0)
{
variableX = 15.0;
}

[fysiks]

variableX = floatclamp( MAXm/400.0, 15.0, 30.0 )
