- pure nothrow @nogc @safe floatcos(floatx);
 pure nothrow @nogc @safe doublecos(doublex);
 pure nothrow @nogc @safe realcos(realx);
- Returns cosine of x. x is in radians.Special Values x cos(x) invalid? NAN NAN yes ±∞ NAN yes Bugs:Results are undefined if |x| >= 264.
- pure nothrow @nogc @safe floatsin(floatx);
 pure nothrow @nogc @safe doublesin(doublex);
 pure nothrow @nogc @safe realsin(realx);
- Returns sine of x. x is in radians.Special Values x sin(x) invalid? NAN NAN yes ±0.0 ±0.0 no ±∞ NAN yes Bugs:Results are undefined if |x| >= 264.
- pure nothrow @nogc @safe longrndtol(floatx);
 pure nothrow @nogc @safe longrndtol(doublex);
 pure nothrow @nogc @safe longrndtol(realx);
- Returns x rounded to a long value using the current rounding mode. If the integer value of x is greater than long.max, the result is indeterminate.
- pure nothrow @nogc @safe floatsqrt(floatx);
 pure nothrow @nogc @safe doublesqrt(doublex);
 pure nothrow @nogc @safe realsqrt(realx);
- Compute square root of x.Special Values x sqrt(x) invalid? -0.0 -0.0 no <0.0 NAN yes +∞ +∞ no 
- pure nothrow @nogc @safe floatldexp(floatn, intexp);
 pure nothrow @nogc @safe doubleldexp(doublen, intexp);
 pure nothrow @nogc @safe realldexp(realn, intexp);
- Compute n * 2expReferences frexp 
- pure nothrow @nogc @safe floatfabs(floatx);
- Compute the absolute value.
 It is implemented as a compiler intrinsic.Special Values x fabs(x) ±0.0 +0.0 ±∞ +∞ Parameters:float xfloating point value Returns:|x|References equivalent to std.math. fabs
- pure nothrow @nogc @safe doublefabs(doublex);
- dittoCompute the absolute value.
 It is implemented as a compiler intrinsic.Special Values x fabs(x) ±0.0 +0.0 ±∞ +∞ Parameters:double xfloating point value Returns:|x|References equivalent to std.math. fabs
- pure nothrow @nogc @safe realfabs(realx);
- dittoCompute the absolute value.
 It is implemented as a compiler intrinsic.Special Values x fabs(x) ±0.0 +0.0 ±∞ +∞ Parameters:real xfloating point value Returns:|x|References equivalent to std.math. fabs
- pure nothrow @nogc @safe floatrint(floatx);
 pure nothrow @nogc @safe doublerint(doublex);
 pure nothrow @nogc @safe realrint(realx);
- Rounds x to the nearest integer value, using the current rounding mode. If the return value is not equal to x, the FE_INEXACT exception is raised. nearbyint performs the same operation, but does not set the FE_INEXACT exception.
- pure nothrow @nogc @safe floatyl2x(floatx, floaty);
 pure nothrow @nogc @safe doubleyl2x(doublex, doubley);
 pure nothrow @nogc @safe realyl2x(realx, realy);
 pure nothrow @nogc @safe doubleyl2xp1(doublex, doubley);
 pure nothrow @nogc @safe realyl2xp1(realx, realy);
- Building block functions, they translate to a single x87 instruction.
- TtoPrec(T : float)(floatf);
 TtoPrec(T : float)(doublef);
 TtoPrec(T : float)(realf);
 TtoPrec(T : double)(floatf);
 TtoPrec(T : double)(doublef);
 TtoPrec(T : double)(realf);
 TtoPrec(T : real)(floatf);
 TtoPrec(T : real)(doublef);
 TtoPrec(T : real)(realf);
- Round argument to a specific precision.D language types specify only a minimum precision, not a maximum. ThetoPrec() function forces rounding of the argumentfto the precision of the specified floating point type T. The rounding mode used is inevitably target-dependent, but will be done in a way to maximize accuracy. In most cases, the default is round-to-nearest.Parameters:T precision type to round to float fvalue to convert Returns:f in precision of type T
