List of 128-Bit Long Double Numerical Manipulation Subroutines

The following subroutines perform numerical manipulation of floating-point numbers stored in the 128-bit long double data type. These subroutines do not support the 64-bit long double data type. Applications that use the 64-bit long double data type should use the corresponding double-precision subroutines.

acosl Computes the inverse cosine of a floating-point number in long double format.
asinl Computes the inverse sine of a floating-point number in long double format.
atan2l Computes the principal value of the arc tangent of x/y, whose components are expressed in long double format.
atanl Computes the inverse tangent of a floating-point number in long double format.
ceill Computes the smallest integral value not less than a specified floating-point number in long double format.
coshl Computes the hyperbolic cosine of a floating-point number in long double format.
cosl Computes the cosine of a floating-point number in long double format.
erfcl Computes the value of 1 minus the error function of a floating-point number in long double format.
erfl Computes the error function of a floating-point number in long double format.
expl Computes the exponential function of a floating-point number in long double format.
fabsl Computes the absolute value of a floating-point number in long double format.
floorl Computes the largest integral value not greater than a specified floating-point number in long double format.
fmodl Computes the long double remainder of a fraction x/y, where x and y are floating-point numbers in long double format.
frexpl Expresses a floating-point number in long double format as a normalized fraction and an integral power of 2, storing the integer and returning the fraction.
