These are standard C programming Mathematical Functions, and are only listed here as a quick reference.
Functions using Float variables
sqrtf
1 | extern float sqrtf (float x); |
Returns the square root of the supplied float x, as a float. x must be greater than 0.
expf
1 | extern float expf (float x); |
Returns the exponential of the supplied float x, as a float.
logf
1 | extern float logf (float x); |
Returns the natural logarithm of the supplied float x, as a float. x must be greater than 0.
log10f
1 | extern float log10f(float x); |
Returns the base 10 logarithm of the supplied float x, as a float. x must be greater than 0.
powf
1 | extern float powf (float x, float y); |
Returns the x to the power y of the supplied floats x and y, as a float.
sinf
1 | extern float sinf (float x); |
Returns the sine of float x, as a float.
cosf
1 | extern float cosf (float x); |
Returns the cosine of float x, as a float.
tanf
1 | extern float tanf (float x); |
Returns the tangent of float x, as a float.
asinf
1 | extern float asinf (float x); |
Returns the inverse sine (sin-1) of float x, as a float.
acosf
1 | extern float acosf (float x); |
Returns the inverse cosine (cos-1) of float x, as a float.
atanf
1 | extern float atanf (float x); |
Returns the inverse tangent (tan-1) of float x, as a float.
atan2f
1 | extern float atan2f(float y, float x); |
Returns the inverse tangent of float y over float x (tan-1(X/Y)), as a float.
fast_fabsf
1 | extern float fast_fabsf (float y); |
Returns the absolute value of float y, as a float.
