Code:

{$ccode p=RAX}

float* a = 0x00102ACC;//4 bytes next to the HP
float number = 16.00f;

//*a = 2.0f //this works as expected
*a=sqrtf(number);//this does not work(the float gets conveted to double and it fucks up the sqrtf call)


it produces this assembly:


It converts the float to a double, and that breaks the call, noping the 2 instructions underlined in red, fixes the call.

try defining sqrtf as a function that takes a float and returns a float

now it thinks it takes an int and returns an int


extern float sqrtf(float v);
