Module float_extras::f64

Functions

copysign	copysign returns a value whose absolute value matches that of x, but whose sign bit matches that of y.
erf	erf returns the error function of x, defined as
erfc	erfc returns the complementary error function of x, that is, 1.0 - erf(x).
fdim	fdim returns the positive difference, max(x-y,0), between their arguments.
fma	fma computes x * y + z. The result is rounded as one ternary operation according to the current rounding mode.
fmod	fmod computes 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	frexp is used to split the number x into a normalized fraction and an exponent which is stored in exp.
ilogb	iligb returns the exponent part of their argument as a signed integer.
ldexp	ldexp returns the result of multiplying the floating-point number x by 2 raised to the power exp.
lgamma	lgamma returns the natural logarithm of the absolute value of the Gamma function.
logb	logb extracts the exponent from the internal floating-point representation of x and return it as a floating-point value.
lround	lround rounds their argument to the nearest integer value, rounding away from zero.
modf	modf breaks the argument x into an integral part and a fractional part, each of which has the same sign as x.
nextafter	nextafter returns 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	remainder 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	remquo computes the remainder and part of the quotient upon division of x by y.
scalbn	scalbn multiplies their first argument x by FLT_RADIX (probably 2) to the power of exp, that is:
tgamma	tgamma calculates the Gamma function of x.
