Functions
copysign |
These functions return a value whose absolute value matches that of x, but whose sign bit matches that of y. |
erf |
These functions return the error function of x, defined as |
erfc |
These functions return the complementary error function of x, that is, 1.0 - erf(x). |
fdim |
These functions return the positive difference, max(x-y,0), between their arguments. |
fma |
These functions compute x * y + z. The result is rounded as one ternary operation according to the current rounding mode. |
fmod |
These functions compute the floating-point remainder of dividing x by y. The return value is x - n * y, where n is the quotient of x / y, rounded toward zero to an integer. |
frexp |
These functions are used to split the number x into a normalized fraction and an exponent which is stored in exp. |
ilogb |
These functions return the exponent part of their argument as a signed integer. |
ldexp |
These functions return the result of multiplying the floating-point number x by 2 raised to the power exp. |
lgamma |
These functions return the natural logarithm of the absolute value of the Gamma function. |
logb |
These functions extract the exponent from the internal floating-point representation of x and return it as a floating-point value. |
lround |
These functions round their argument to the nearest integer value, rounding away from zero. |
modf |
These functions break the argument x into an integral part and a fractional part, each of which has the same sign as x. |
nextafter |
These functions return the next representable floating-point value following x in the direction of y. If y is less than x, these functions will return the largest representable number less than x. |
remainder |
These functions compute the remainder of dividing x by y. The return value is x-ny, where n is the value x / y, rounded to the nearest integer. If the absolute value of x-ny is 0.5, n is chosen to be even. |
remquo |
These functions compute the remainder and part of the quotient upon division of x by y. |
scalbn |
These functions multiply their first argument x by FLT_RADIX (probably 2) to the power of exp, that is: |
tgamma |
These functions calculate the Gamma function of x. |
