inline bool isinf(float32 x) §
Check x is positive or negative infinity.
inline bool isfinite(float32 x) §

inline bool signbit(float32 x) §
Return sign of x.
template <Denorm denorm_mode> inline float32 add(float32 in1, float32 in2) §
Addition.
template <Denorm denorm_mode> inline float32 mul(float32 in1, float32 in2) §
Multiplication.
template <Denorm denorm_mode> inline bool eq(float32 in1, float32 in2) §
Compare two float32 values for equality.
template <Denorm denorm_mode> inline bool lt(float32 in1, float32 in2) §
Check in1 less than in2.
template <Denorm denorm_mode> inline bool gt(float32 in1, float32 in2) §
Check in1 greater than in2.
template <Denorm denorm_mode> inline float32 sub(float32 in1, float32 in2) §
Subtract in2 from in1.
inline float32 rcp(float32 x) §
Reciprocal 1 / x.
inline float32 exp2(float32 x) §
2x
inline float32 exp(float32 x) §
ex
inline float32 expm1(float32 x) §
Calculate ex − 1. Denorm
inputs and outputs are supported. For smaller values of x,
expm1(x) may be more accurate than
exp(x)-1.
inline float32 log2(float32 x) §
log2(x)
inline float32 log(float32 x) §
ln(x)
inline float32 log10(float32 x) §
log10(x)
inline float32 log1p(float32 value) §
Calculate ln(x + 1). Denorm
inputs and outputs are supported. For small values of x,
log1p may be more accurate than log(1+x).
inline float32 logb(float32 x) §
Calculate the floating-point value of the unbiased exponent part of
log(x). If x is a subnormal value, the result
of log2(mantissa part of x)-126 is returned.
inline int32 ilogb(float32 x) §
Return the signed integral value of the unbiased exponent part of
log(x). If x is a subnormal value, the result
of log2(mantissa part of x)-126 is returned.
inline float32 atan(float32 x) §
Return the principal values of arctangent. Denorm inputs and outputs are supported.
inline float32 pow(float32 base, float32 expo) §
baseexpo
inline float32 sin(float32 x) §
sin(x)
with x in radians.
inline float32 cos(float32 x) §
cos(x)
with x in radians.
template <Denorm denorm_mode> inline float32 min(float32 x, float32 y) §
Return the smaller of x and y. A NaN is
treated as missing data, and the other value will be returned.
template <Denorm denorm_mode> inline float32 max(float32 x, float32 y) §
Return the larger of x and y. A NaN is
treated as missing data, and the other value will be returned.
template <Denorm denorm_mode> inline float32 ceil(float32 x) §
Return the smallest integer not less than x: ⌈x⌉
template <Denorm denorm_mode> inline float32 floor(float32 x) §
Return the largest integer not greater than x: ⌊x⌋
template <Denorm denorm_mode> inline float32 round(float32 x) §
Return the nearest integer to x, rounding halfway away
from zero.
template <Denorm denorm_mode> inline float32 trunc(float32 x) §
Return the nearest integer not greater in magnitude than
x.
template <Denorm denorm_mode> inline float32 dim(float32 x, float32 y) §
The positive difference between x and y:
max(x - y, 0). Return NaN if x or
y is NaN.
template <Denorm denorm_mode> inline float32 abs(float32 x) §
Return the absolute value of x: |x|
